Q Summary

Pentax produces a small-sensor digital camera with interchangeable lenses, a first for the digital camera industry. If your interchangeable-lens camera sits at trang chủ on the shelf because it's too big, the Pentax Q could be the camera you're looking for, but is it too extreme for the rest of us?

Pros

The first genuinely compact--almost pocket-friendly--compact system camera, paired with equally small, interchangeable lenses. Great ergonomics for the size, and it feels lượt thích a real camera, not a computer with a lens.

Bạn đang xem: Đánh giá pentax q

Cons

Very restrictive sầu lens selection at launch. All but two current lenses have sầu severe limitations in functionality. Performance is sluggish, và image quality trails large-sensor cameras by some distance.

Price và availability

Available since September 2011, the Pentax Q is currently available in two kits in the US market. The single-lens kit includes the Pentax 01 Standard Prime lens, và has a danh mục price of US$750. A twin-lens kit available at some retailers adds in the Pentax 02 Standard Zoom lens, & sells for around US$1,050.

Pentax Q Review

by Shawn Barnett, Mike Tomkins, và Zig WeidelichHands-on Preview posted June 23, 2011Review posted April 26, 2012

It wasn"t long ago I had the pleasure of running around town with one of the largest interchangeable lens cameras on the market, the Pentax 645D. It was big, but handled well, with excellent optics and a very high-resolution sensor. Today the contrast was dramatic, carrying the very tiny Pentax Q, a small interchangeable lens camera. The experience was very different, but it was still a Pentax, a company that"s pushing beyond lots of boundaries lately. The Pentax Q has smaller optics và a smaller, lower-resolution sensor. Indeed, it"s so small it fits in a pocket and conceals easily in a palm--or behind an iPhone. It could even hang--as our illustration demonstrates--from a keychain, were it not worthy of better daily care than that.


*

Although its smaller 50%.3"-sized sensor can"t compete with comparably priced SLRs & CSCs, we"re impressed with the execution on the Pentax Q. It"s easier lớn make a case for comparing it khổng lồ chất lượng enthusiast cameras lượt thích the Canon G12, where its image chất lượng fares better by comparison, albeit at a $300 price premium for the luxury of interchangeable lenses.

Build. With all of its latest digital SLRs, Pentax has demonstrated its ability khổng lồ build a high unique camera, and the Pentax Q"s magnesium alloy build feels more serious than a simple pocket camera, despite its Lilliputian stature. Pentax"s impressive line of Limited SLR lenses, in particular, seem khổng lồ be echoed in the chất lượng of the 8.5mm Standard Prime kit lens. Both the lens & mount are steel và have sầu a tight, precision fit.

Dials and buttons, too, are of good unique, with firm detents on the dials, and audible, tactile clicks on the buttons: an important feature with such small buttons.

Most surprising is how natural it feels to use the Pentax Q. It"s smaller than the average pocket long zoom, but still feels about lượt thích using one, thanks lớn the small finger & thumb grip. In something of an optical illusion, the lens seems to lớn be closer to lớn the grip side of the camera than the other, but it"s actually about two millimeters lớn the right.

Ultimately, the Pentax Q is built more lượt thích an SLR, but it feels as familiar as a quality pocket camera.

*
With the lens off, you can see the small sensor that allows such a small camera và such small lenses. It"s somewhat surprising Pentax didn"t choose a 1/1.7" sensor, as are used in the Canon G12 và competing designs. But the 12.4-megapixel CMOS sensor is backlit, which should offer better performance in low light, và lower noise overall.


The front view of the Pentax Q shows an IR remote sensor embedded into the grip, an AF-assist lamp, the lens release button, and two holes for the stereo microphones. The peculiar dial on the right of the lens is used to lớn quickly select among a selection of Smart Effects or other available filters. Via a thực đơn, you piông chồng which filters you want lớn have at each setting; returning the dial khổng lồ the Trắng dot turns all filters off.

Though the flash looks like any other built inlớn a pocket camera, it is anything but ordinary. It doesn"t just pop up, it swings up and over to the right (see photo lớn below) khổng lồ help minimize red-eye & to lớn clear larger lenses and lens hoods. Someone deserves an award for this bit of engineering. Here"s hoping Pentax makes a wad of cash licensing the kiến thiết to other companies. The flash will also fire from its nested position.

*
A look at the top of the Pentax Q shows the 8.5mm lens (47mm equivalent), called the 01 Standard Prime. Its knurled ring makes mounting & removal easy, và the front focus ring does not offer physical control over focus, instead feeding ring position data khổng lồ the focusing system as you turn it. Unlượt thích many competing fly-by-wire designs, focus tracks the ring"s movement very well, making it relatively pleasant to use.

The small popup flash is released via the slider just behind it. It takes a little practice lớn release the flash without your fingers getting in the way. Next lớn that is the Playbaông chồng button, something we"d have preferred to lớn see on the bachồng, but admittedly there"s very little room on the Pentax Q. The hot shoe looks relatively massive sầu on the Q. It"s compatible with Pentax"s current line of flashes, but the kích cỡ and weight of larger strobes will present handling issues. Five sầu holes mark the position of the speaker. The small power button is right of that, and the gunmetal shutter button rises fairly high from the camera toàn thân, offering a very soft half-press with a clean break at full press for a very good feel.

The Mode dial sits atop and dictates the shape of the small fingertip grip, just as the Rear dial describes the shape of the rear thumbgrip. Strap lugs are molded into the top plate of the Pentax Q, presumably also of magnesium alloy.

*
Tightly fitted inlớn the small chassis is the 460,000-dot, 3-inch TFT LCD with a 170 degree viewing angle. Unlượt thích the Sony NEX-C3 & Panasonic GF3, two cameras also pushing the kích thước barriers for interchangeable lens cameras, the Pentax Q doesn"t take the minimadanh sách approach lớn the camera"s interface khổng lồ eliminate buttons. Instead they take the approach that"s worked for pocket digital cameras for years: small buttons; no scroll wheels, soft buttons, or touchscreens. I can see some objecting lớn the use of such small buttons, but those who don"t like small buttons have sầu no business looking at a camera this small to lớn begin with. Most of the buttons are recessed & stiff enough to avoid accidental activation, yet they yield lớn gentle, inward pressure with a soft cliông xã. The four outer navigation buttons are beveled upward from the center out for easier tactile differentiation from the other buttons, which are admittedly quite cthua.


*

Magnesium alloy. The Pentax Q feels very solid thanks to lớn its magnesium alloy toàn thân.


Most of the buttons are marked, & so self-explanatory. The markings are small enough that those with poor near vision might have sầu trouble, but they would also have sầu trouble with the interfaces on the C3 & GF3, so I think Pentax has made a good choice here. Just above sầu the Exposure Compensation button is a secondary IR remote port, compatible with the same remote control units as are the company"s larger SLRs.

It"s when I look at the cavities necessary khổng lồ house the battery, memory thẻ, pop-up flash, & sensor that I marvel at the electronic engineering required khổng lồ pachồng the circuit boards & processors inlớn such a small remaining space. Internal space is further constrained by buttons, dials, the LCD, ports, & even the tripod mount. It is an impressive achievement, even if the sensor is quite small.


*

Getting back to that pop-up flash, it is a bit of a marvel itself, demonstrating that there is a way to lớn get built-in flashes a little further from the lens through the application of clever engineering. First, with a slide of the mechanical release, a springloaded plunger rises from inside the Pentax Q"s toàn thân, then opposing sprung levers both lift the flash và màn chơi it again in its final resting position. A simple downward press puts all baông chồng into place, quite well concealed và compact.

Size and Weight. Dimensions are 3.9 x 2.3 x 1.2 inches (98 x 58 x 31mm). Weight with a memory card, battery, và lens is 8.5 ounces (241g), và 7.1 ounces (202g) with the lens removed. That makes the lens about 1.4 ounces (39g) light, at least a partial answer lớn the question of why you"d make an interchangeable lens camera with so small a sensor.


*

Connectivity. The Pentax Q includes USB 2.0 High Speed data connectivity, as well as both NTSC / PAL composite standard definition đoạn Clip output, & a Type-D Micro HDXiaoMi MI high definition output; both of these are accessed via a small rubber door on the bottom of the camera. Impressively, given the kích thước, the Pentax Q also includes infrared remote control receivers on both the front & rear of the camera, ensuring the remote works whether you"re behind the camera or in front of it.


Storage. The Pentax Q accepts Secure Digital storage truyền thông, including the newer, higher capađô thị SDHC and SDXC types. Images are stored as 12-bit .DNG RAW files, or 8-bit JPEGs in one of three quality levels. Movies are stored as .MP4 files. The door is released with a slide to lớn the rear, after which it swings open toward the front of the camera under spring pressure.


nguồn. A proprietary D-LI68 lithium-ion rechargeable battery allows the Pentax Q khổng lồ provide for 230 shots on a charge to lớn CIPA testing standards (một nửa flash usage), or 160 minutes of continuous playbachồng. This door also opens with a firm pull khổng lồ the rear, followed by a springloaded swing toward the front.

 

Pentax Q Technical Details

Sensor. The modest size of Pentax"s Q compact system camera has been achieved largely thanks khổng lồ Pentax"s choice of a một nửa.3"-type image sensor, where the company"s main rivals have sầu all chosen lớn use significantly larger sensors in their interchangeable-lens models. Compared lớn a Micro Four Thirds camera, the Pentax Q"s imager has just slightly less than 1/8th the light gathering area, while APS-C models have sầu an advantage of closer to lớn 13x.

*
That decision has proven lớn be something of a double-edged sword. On the one h&, it has allowed Pentax khổng lồ craft a camera which it can confidently clayên to lớn be the world"s smallest, lighkiểm tra interchangeable-lens digital camera body toàn thân. On the other h&, all other things being equal it also leaves the Pentax Q unable khổng lồ challenge its compact system camera rivals in terms of high ISO noise performance, & nor can it rely on lens aperture control to lớn provide the same shallow depth of field for creative sầu effect. On the plus side, it matches or betters its main small-sensor rivals--enthusiast fixed-lens cameras lượt thích the Canon G12--and there"s certainly something khổng lồ be said for the importance of size và weight in camera design. If your camera gets left behind when you"re out & about, the best image quality in the world is of little use when an unanticipated pholớn opportunity presents itself.

Aiming khổng lồ achieve sầu the best high ISO noise performance possible with its chosen sensor form size, Pentax has selected a backside-illuminated, 12.4 effective megapx CMOS image sensor for the Q. The backside-illuminated design places circuitry on the rear (non-illuminated) side of the sensor, allowing the greakiểm tra possible area on the light-gathering side khổng lồ be devoted khổng lồ photodiodes. Total resolution of the Pentax Q"s chip is 12.75 megapixels, và the maximum dimensions of output images are 4,000 x 3,000 pixels. The sensor has a 4:3 aspect ratio, và the Pentax Q also offers cropped 3:2, 16:9 & 1:1 aspect modes. ISO sensitivity ranges from 125 lớn 6,400 equivalents in 1/3 EV steps, & can be controlled automatically or manually throughout the entire range.

Lens mount. Accompanying the Pentax Q"s image sensor is a new stainless steel lens mount that"s significantly smaller than the K-mount used on Pentax"s digital SLR cameras. Dubbed the Q-mount, this has an outer diameter that"s almost one-third smaller than that of the K-mount, allowing a reduction not only in camera toàn thân size, but also in the form size of attached lenses. Like other compact system cameras, with no need to lớn accommodate a bulky mirror box, optical viewfinder, dedicated autofocus & metering sensors, etc., Pentax has been able to lớn reduce flange bachồng distance--which relates closely lớn body toàn thân thickness--by a whopping margin of close to lớn 80%. Flange baông chồng distance for the Pentax Q is just 9.2mm, around half or less than that of the Sony E-mount (18mm), Micro Four Thirds mount (20mm), & Samsung NX mount (25.5mm).


As an aside, there"s an interesting back story behind the names of Pentax"s lens mounts. With the introduction of the K2, KX & KM film cameras in 1975, the company--then known as Asahi Pentax--decided lớn replace its venerable M42 screwmount with a newer, easier-to-use bayonet type. Dubbed the K-mount, the new mount"s initial stood for "King"--an indication of Asahi"s belief in their product which also happened khổng lồ dovetail nicely with their marketing efforts. (At the time, the Asahi Pentax biểu tượng logo included a crown, while their cameras appeared in advertisements alongside a deông xã of playing cards, with a king thẻ shown prominently.) Every king needs his queen, và with the debut of the Pentax Q camera, the new Q-mount assumes that role.


Optics. Alongside the camera"s launch, Pentax revealed its first five sầu Q-mount lens models, split into lớn two distinct groups, which Pentax nhật bản refers to lớn as the "High-Performance Series" and "Unique Series" respectively. High Performance lenses feature metal mounts và Pentax"s SP (Super Protect) lens coating, offer 40.5milimet filter threads, & include both a built-in ND filter, và an in-lens shutter mechanism that allows một nửa,000 second flash sync with the internal flash. Unique-series lenses are aimed at lower cost, và replace the metal mount with a plastic one, much lượt thích the company"s DA-L lenses on K-mount cameras. They also drop autofocus capability, the in-lens shutter mechanism and ND filter, don"t include filter threads, and--with the sole exception of the Fish-Eye lens--don"t feature the Pentax SP lens coating.

The High Performance series currently (Feb 2012) includes two lens models. The PENTAX 01 Standard Prime kit lens, which ships with the camera itself, has a 35mm-equivalent focal length of 47mm, và an f/1.9 maximum aperture. The sole zoom lens, and the only High Performance-series lens available for separate purchase, is the PENTAX 02 Standard Zoom. This offers up a 35mm-equivalent focal length range of 27.5-83milimet, with a maximum aperture that varies from f/2.8 khổng lồ f/4.5 across the range.

The Unique series lens lineup currently includes three models, all of which are manual-focus only. The PENTAX 03 Fish-Eye is the sole model in the series to include an SP coating, & has a 17.5mm equivalent focal length, a 160° field of view, và a pan-focus kiến thiết. The remaining two lenses are intended for creative use, và will likely appeal lớn fans of lomo photography. Dubbed "toy lenses," the Pentax 04 Toy Lens Wide & Pentax 05 Toy Lens Telephokhổng lồ equate lớn 35milimet và 100mm lenses in the 35milimet format, respectively, và each introduces various aberrations inkhổng lồ final images.


Stabilization. Despite the huge reduction in body toàn thân và mount size compared to its K-mount cameras, Pentax has still left sufficient room within the Q-mount"s image circle to lớn allow for it lớn include its sensor shift image stabilization mechanism. Like that used in its SLRs, the Pentax Q"s Shake Reduction system is said khổng lồ be good for a four-stop correction, và thanks to the in-toàn thân design, it"s available for all Q-mount lenses.

Dust reduction. The Pentax Q also includes the company"s DR II dust reduction system, similar khổng lồ those used in its flagship K-5 / K-7 & 645D digital SLRs. Based around a piezoelectric element, this system represents a worthwhile step up in efficacy from the sensor shift-based systems used in many consumer DSLRs.


Performance. In its Continuous Hi-speed burst shooting mode, the Pentax Q can capture images at a swift five frames per second, although burst depth is limited khổng lồ just five JPEG frames. By switching khổng lồ the Continuous Lo drive mode, the burst speed falls to lớn 1.5 frames per second, but the buffer depth can be extended lớn a much more useful 100 JPEG frames.

Display. On its rear panel, the Pentax Q offers up a roomy 3.0-inch LCD panel with a total resolution of some 460,000 dots, commonly known as Hđồ họa (half VGA), where each px comprises adjacent red, green, and xanh dots. The Pentax Q"s display is said to offer wide 170-degree viewing angles both horizontally and vertically.


Viewfinder. The Pentax Q doesn"t offer any khung of built-in optical viewfinder, & unlượt thích some compact system cameras, it can"t accept an external electronic viewfinder either. Pentax does offer a shoe-mounted O-VF1 optical viewfinder accessory, but it only includes guide marks for the 47mm kit lens, & this combined with its $250 price tag will correctly persuade most photographers lớn instead rely solely on the Q"s LCD display.

Focusing. Like its main competitors, the Pentax Q uses contrast-detection autofocusing, operating on data streaming from the main image sensor. The Pentax Q"s 25-point autofocus system has both single và continuous-servo operating modes, & includes a face detection function. Of course, it"s also possible to lớn focus manually if desired.

Exposure. As you"d expect, the Pentax Q includes the usual selection of Program, Aperture-priority, Shutter-priority, and Manual exposure modes. There"s also an Aukhổng lồ Picture mode that can automatically select between Standard, Portrait, Landscape, Macro, Night Scene Portrait, Night Scene, Blue Sky, & Forest shooting modes as the camera deems appropriate. For those who want a modicum more control without the need lớn understvà basic exposure variables, there"s also a Scene mode that offers a healthy selection of modes: Portrait, Landscape, Macro, Moving Object, Night Scene Portrait, Sunphối, Blue Sky, Night Scene, Night Snap, Food, Pet, Kids, Forest, Surf và Snow, Backlight Silhouette, Candlelight, Stage Lighting, Museum, plus three JPEG-only modes, Night Scene HDR, Quick Macro, và HDR.

Mechanical shutter speeds from 1/2,000 khổng lồ 30 seconds are available, và are controlled with an in-lens shutter mechanism in the Pentax 01 Standard Prime và Pentax 02 Standard Zoom lenses. The Fish-Eye and Toy lenses all laông xã an in-lens shutter mechanism, và since the camera body toàn thân itself doesn"t include a mechanical shutter, this necessitates use of an electronic shutter when these lenses are attached. Electronic shutter speeds range from 1/8,000 to lớn two seconds, and the electronic shutter can be enabled in the Custom Setting menu to get a combined range of 1/8,000 khổng lồ 30 seconds with shutter-equipped lenses. The Pentax Q also offers a bulb position (not supported with shutterless lenses) in the Manual exposure mode, & this lowers the maximum sensitivity from ISO 6,400 khổng lồ 1,600 equivalent. Three metering modes are available: Multi-segment (no info yet available on how many segments), Center-weighted & Spot. The Pentax Q offers 3.0 EV of exposure compensation, in 1/3 EV steps. There"s also a three-frame bracketing mode, plus an exposure loông xã function which can be tied lớn either the Shutter or Green buttons.


Flash. The Pentax Q includes a built-in five-mode popup flash strobe with a guide number of 7 meters / 23 feet at ISO 200. At first glance it looks to lớn be fixed in place, và it can in fact be fired in the lowered position if desired, but it also includes an unusually tall articulation mechanism that allows coverage sufficient for a 28mm-equivalent wide angle lens. There"s also a full-sized hot shoe compatible with all of Pentax"s current flash strobes, although larger units--we tried the AF540FGZ, for example--prove very unwieldy, when paired with the Pentax Q"s impressively compact toàn thân. The internal flash provides a red-eye reduction function, and operating modes include Aukhổng lồ, Aukhổng lồ + Redeye, On, On + Redeye, Slow Sync, Slow Sync + Redeye, Trailing Curtain Sync, & Off.

When using the internal flash strobe, X-sync is possible at một nửa,000 second, but only if the attached lens includes an internal shutter mechanism -- something true only of the High Performance lens series. X-sync falls to 1/250 second with an external flash strobe, and plummets to just 1/13 second for Unique-series lenses that must rely on an electronic shutter. Flash exposure compensation is possible within a range of -2.0 khổng lồ +1.0 EV.

HDR imaging. Like all of Pentax"s recent DSLRs, the Pentax Q includes in-camera high dynamic range imaging, which automatically blends three shots in-camera to yield a single frame. As with the company"s DSLR HDR mode, the Pentax Q can automatically microalign the source images, allowing the HDR mode khổng lồ be used handheld.

Creative. A particularly unusual feature of the Pentax Q is its Smart Effect functionality, which offers up a selection of Brilliant Color, Unicolor Bold, Vintage Màu sắc, Cross Processing, Warm Fade, Tone Expansion, Bold Monochrome, Watercolor, & Vibrant Color Enhance effects. Each can be assigned to lớn the dedicated front dial lớn provide five-step control (1-4 & Off) over the strength of the effect. Alternatively, the dial can be set lớn switch between user-selected effect types. There are also a variety of capture-time digital filter modes, as seen in past Pentax SLR cameras. These include Toy Camera, High Contrast, Shading, Slyên, HDR, Invert Color, Extract Màu sắc, màu sắc, Watercolor, Posterization, & Fisheye. Finally, a JPEG-only "Blur Control" mode attempts to lớn simulate reduced depth of field, mimicking the look of images shot with larger-sensor cameras.

User modes. Pentax Q shooters can also store a handful of key camera settings--white balance mode, custom image mode, & digital filter--into lớn one of three User modes, allowing quick reHotline of these settings for use in a specific shooting situation. Unfortunately, you can"t store và recall other settings at the same time.


Video. As well as still images, the Pentax Q can capture 1,920 x 1,080 px high definition Clip (commonly called 1,080p or "Full HD") at a rate of 30 frames per second. If storage or bandwidth are more important than resolution, you can also select from high-def 1,280 x 720 pixel (720p) and standard-def 640 x 480 (VGA) at the same rate of 30 fps. Unlượt thích Pentax"s digital SLR cameras, the Q uses H.264 AVC compression, which is far more efficient in terms of storage space, albeit with a greater requirement in terms of processing power to edit the resulting Clip on a computer.

Pentax Q kích cỡ comparisons

Pentax Q vs Pentax A110

*
*
*

Arthur Etchells, IR"s Director of Strategic Development, jumped in his time machine và acquired this pristine Pentax Aukhổng lồ 110 Super, circa 1982, for comparison with the Pentax Q. Its lens mount was even smaller, as the photos show. It was a true SLR, complete with pentaprism. Its relatively squat profile was allowed by the small stature of the 110 film cartridge, while the Pentax Q"s kích thước is dictated partially by the 3-inch LCD. The Aukhổng lồ 110 did not have a hot shoe, though it is less than a millimeter taller than the Pentax Q.
From the front with the lenses off, you get an even better idea of how small the Pentax Auto lớn 110 Super"s mount is. The two-bladed shutter inside the Auto 110"s lens mount makes the film kích cỡ seem smaller than it is. The Aukhổng lồ 110 was unusual in featuring a combined leaf shutter / aperture diaphragm in the camera body toàn thân, while the corresponding lenses had a fixed f/2.8 aperture. Between exposures, the shutter / aperture mechanism was held partially open khổng lồ allow image framing through its optical viewfinder, while the mirror beneath provided a light seal when lowered to prevent film exposure. An interesting side effect of this design was that full-aperture imaging was only available for exposures 1/30th second or longer. The view from the baông xã with the film door open hence gives a better comparison of the Pentax Q"s 1/2.3" sensor to lớn the 110milimet film size of the Pentax Auto 110.
Now of course we realize that the Pentax Q goes up better against the Canon G12 in terms of sensor kích thước, but it also competes in the Compact System Camera market, và it compares quite favorably khổng lồ the lademo small entry in that category, the Panasonic GF3. Both have pop-up flashes và a smallish grip, but the Pentax Q has a few more controls, and no touchscreen. The GF3 also has a Movie record button that the Pentax Q lacks, while the Q has a hot shoe that the GF3 discarded.
Neck & nechồng with the GF3, the Sony NEX-C3 is also larger than the Pentax Q. Where the Sony C3 uses soft buttons và a dial for most controls, the Pentax Q goes for more conventional small buttons with bold labels. It"s arguable that Pentax"s approach will be more readily understood by most pocket digital camera users. The Q"s built-in flash makes the camera seem smaller when compared to the NEX-C3 with its accessory flash mounted.

 

Pentax Q Field Test

by Mike Tomkins

*
On first acquainting myself with the Pentax Q, I was pleasantly surprised by how well it handled. This is a small camera--really small, by interchangeable-lens camera standards--& at over six feet tall, there"s no getting around the fact that I have pretty big hands. I was expecting things lớn feel rather cramped, and while they"re certainly compact, I actually found the Q very comfortable to lớn shoot with, overall. It helps that the Q"s lenses are equally small, and hence the overall package is well-balanced. That"s not to say that it"s perfect ergonomically; I personally found the ISO / Up Arrow button slightly uncomfortable khổng lồ press, due to lớn its proximity to lớn the thumb grip bulge at the top right corner of the rear panel. Moving the four-way arrow pad a little closer khổng lồ the LCD would have sầu helped The Menu button also felt uncomfortably cchiến bại to lớn the corner of the camera toàn thân. Given the space Pentax had khổng lồ work with, though, I think they did an excellent job with the Q"s ergonomics, not to lớn mention the aesthetics. (The retro styling is very attractive, bringing more attention around town than I can rethành viên in quite some time. I quickly got used lớn people coming up và asking me about the Q.)

One feature did feel lượt thích something of a missed opportunity, though. The Quiông chồng dial on the front panel is a great idea, but the menu of features which can be assigned to lớn this dial is very brief, và really only of interest lớn JPEG shooters: Smart Effects, Custom Image settings, Digital Filters, and Aspect Ratio settings. My workflow is pretty-much exclusively RAW-based these days, & I"d have loved to see a greater selection of features available via the Quichồng dial. My ikhuyến mãi would have been for it to provide access to lớn complete settings groups, much lượt thích the User Mode function on Pentax"s digital SLRs. (In fact, my heart skipped a beat when I discovered the User 1 to User 3 option via the Quiông xã Dial"s Smart Effects function, but that hope was dashed when I realized that these "User" options store only the White Balance, Custom Image, và Digital Filter settings.)

The Quiông chồng Dial defaults lớn selecting one of four Smart Effects, which combine Custom Image and Digital Filter functions into lớn a single effect, as shown above.

I was fortunate lớn have a very complete Pentax Q kit on h& for my reviews, including not just the camera, but all current Q-mount lenses, the O-VF1 viewfinder accessory, và a 40.5milimet polarizing filter that works with both the 01 Standard Prime and 02 Standard Zoom lenses. They even included a small case that I believe was actually intended for one of Pentax"s Optio W-series digicams, but happily consumed the entire kit with space left over. That should tell you just how portable the Q is -- you don"t feel in the least bit weighed down bringing the entire kit everywhere you go. My daily shooter is a Pentax K-5, và so I also had access to the relevant remote controls, flash strobes, etc. to see how the Q fit inlớn the larger Pentax ecosystem. (And take it from me, the Q looks decidedly odd with a large AF540FGZ flash strobe mounted in the hot shoe. I try these things so you don"t have lớn be the recipient of strange looks in public when you try it yourself!)


*

There"s lots of detail in this shot with the 01 Standard Prime Lens, but even at just ISO 250, some noise (& noise reduction smudging) is starting to become noticeable.


Both High Performance-series lenses were a pleasure to lớn shoot with. They feel just as high unique as the Q"s body itself, their metal mounts clichồng into place reassuringly when mounted, & although they"re fly-by-wire, focusing manually is easy và accurate. It"s a nice touch that both lenses chia sẻ the same 40.5milimet filter threads, allowing you lớn simply swap filters and lens caps between the pair. It"s a pity that the prime"s 8.5mm focal length is one already covered by the zoom, though. I found that because I"m not typically a prime shooter, & I could already achieve the same focal length with the zoom, I had khổng lồ consciously remind myself that the prime was in my camera bag. It tended to go unused unless I really needed the wider f/1.9 aperture, or I was shooting a relatively static subject that gave sầu me more time khổng lồ think about switching lớn the prime, and framing with my feet. I"d have preferred to lớn see the prime coupled to lớn a more telephoto zoom, & it looks like that wish may come true later this year.

The Unique-series lenses were interesting, but they weren"t really my cup of tea. I"m not the target audience, clearly: while I can see the appeal of the lo-fi look with the right image, I prefer khổng lồ shoot a high-quality photo lớn & then play with effects in post-processing. That way, I still have sầu a high unique original if I decide khổng lồ change my mind about the lo-fi look. I tried lớn put myself in the shoes of the typical cellphone-toting Instagram or Hipstamatic tín đồ, nonetheless. The near impulse-buy pricing of the Unique-series lenses is a clear bonus, as is their extremely light nature. You can slip them in a pants pocket & literally forget that they"re even there. They also still feel reasonably good quality, despite the price và greater usage of plastic in their designs. Unfortunately, they bring so many limitations--no autofocus, no in-lens shutter, no ND filter, fixed aperture, extremely slow 1/13 second X-sync, a very short manual-focus throw, & no filter threads--that shooting with them invariably took me out of the moment, as I tried to rethành viên which features I could or couldn"t use, and how I"d need to lớn work around those limitations. At the price, I"d probably still pick them up, but I have sầu a feeling they"d end up little-used once the novelty wore off. That"s where I found my first real problem with the Pentax Q, & it"s one that may resolve sầu itself as more Q-mount optics are released: right now, there may be five sầu lenses available, but I have sầu a feeling all but the 02 Standard Zoom would spover most of their time languishing untouched in my camera bag.


*

Of the Unique series lenses, the most fun for my money is probably the Pentax 03 Fish-eye, but all lenses in the series have some pretty major functional limitations.


Pentax"s O-VF1 optical viewfinder accessory likewise left me feeling a little conflicted. It"s beautifully made, and yields a very bright, sharp view, as you"d expect given the hefty chunk of glass at its heart. It"s a little tight to lớn slip on and off the hotshoe, but with use I imagine a little wear would make it less fiddly to mount và remove. It"s surprisingly expensive sầu, though: double or more the price of competing system camera viewfinder accessories, and there are no front or rear caps to lớn protect its optics. That made me rather nervous leaving it mounted when I wasn"t actively shooting with it. It also blocks the popup flash, preventing it extending, & while you can at least use the flash in its retracted position, that"s likely to lớn increase the chances of redeye. Nor can you use an external flash strobe with the O-VF1 mounted. Perhaps the biggest issue, though, is that it only includes framing guidelines for the 01 Standard Prime lens. Of course, on the plus side it uses no battery whatsoever, và there"s that gorgeous, bright view. If you plan on shooting almost exclusively with the standard prime, the O-VF1 might be worth considering, but otherwise I"d pass on it.

My Remote Control F & Remote Control O-RC1 both worked perfectly with the Pentax Q. Given that the Q"s body isn"t weather-sealed, the latter is overkill, though. If you don"t own either, I"d suggest picking up the Remote Control F, which is so small you could forget it was in your shirt pocket. I didn"t have sầu access to any of Pentax"s external strobes except my AF540FGZ, và while they worked just fine together, the combination was extremely unwieldy, as I"ve sầu mentioned. Given that the Q"s autofocus system can"t take advantage of the AF assist function of larger strobes, I"d probably recommover staying with the AF200FG, if you really need an external strobe. (And you probably will, if you need to lớn vị much handheld, low-light shooting; the onboard flash has a very clever extension mechanism, but even by compact system camera standards, it"s relatively weak.)

Bump the ISO sensitivity up nearer the maximum, and things start getting pretty blotchy and smeary, as in this ISO 3,200 shot. That said, there"s still quite a lot of fine detail left in the bridge railings.


As I"ve said, I had a lot of fun shooting with the Pentax Q thanks lớn its camera-lượt thích feel. There were, however, a couple of flies in the ointment. Like I said, I"m typically a full-time RAW shooter, but while reviewing cameras I usually switch to RAW+JPEG, so that I can provide out-of-camera images as well. That can be a bit painful with the Pentax Q, because from a reasonably handy 5.3 frames per second in JPEG-only shooting, burst performance and depth falls off a cliff as soon as RAW capture is enabled. Even at just 1.2 frames per second, I could shoot roughly four RAW+JPEG frames, & would then have to lớn wait ten seconds for the buffer lớn clear. Autofocus likewise felt sluggish, and while I didn"t use it very much--this isn"t a camera I"d choose lớn shoot sports with--the tracking autofocus seemed rather hit và miss, frequently forgetting what it was tracking even with a fairly high-contrast subject, & wandering off around the frame at random.

Bachồng home, I found my shots a little disappointing for a camera at this price point. Although the Q"s images had the fairly punchy, Pentax look which I rather like, they tended lớn be rather on the soft side, and that"s at or near the camera"s base ISO sensitivity. Push the sensitivity a bit, & rather heavy-handed noise reduction starts lớn rob images of detail. Personally, I found myself trying lớn stay under ISO 400, but having grown accustomed khổng lồ regularly shooting at ISO 3,200 or even ISO 6,400 with my Pentax K-5, that felt very limiting. Of course, the Q didn"t vày badly compared khổng lồ other cameras at this sensor form size, but that"s the point: its main mirrorless rivals don"t have sầu lớn contkết thúc with a sensor of this form size. Even on a bright, sunny day, that sensor still brings drawbacks, most notably in the difficulty of achieving a shallow depth-of-field effect. Pentax"s Blur Control function aims khổng lồ answer this shortcoming, và in some situations it works surprisingly well. Unfortunately, it"s rather hit & miss, though: the effect occasionally looks very artificial, and even blurs the edges of your subject inkhổng lồ the background. It"s also a shame that since it"s a standalone mode, Blur Control can"t be combined with other functions, meaning many Q owners will simply forget it"s available to lớn them.


*

The Blur Control function can yield some reasonably convincing results with the right shot, although even here, the illusion falls apart when inspected more closely. Note the dark halo around the antennae on the model trams, và the fact that the closer tram"s antenmãng cầu is more blurred than the one behind it, when the reverse should be the case.


I"m conscious that it probably seems I"m being rather hard on the Pentax Q. Perhaps that"s partly down to lớn the fact that I"ve found the company"s SLR cameras so great: you could offer me significantly more expensive cameras, & you still wouldn"t pry my K-5 out of my hands. Sadly, as much as I wanted khổng lồ love sầu the Pentax Q for its tiny, take-anywhere body & unique feel, I found myself leaving it at trang chính entirely too often. Not because it"s too big, like most other interchangeable-lens cameras, but because there always seemed to lớn be another camera on the shelf promising better image quality. As much as ergonomics, feature phối, & unique are an important part of the shooting experience, the quality of the images is key for me.

Were it a straight fight against compact cameras with a similar sensor form size, the Pentax Q would win hands-down. Sadly, its pricing pits it against compact system cameras with much larger sensors, và while none of them come cthua trận to lớn the form size of the Pentax Q, you can argue that they"re at least small enough, compared lớn the typical SLR. In terms of image quality, pitting the Q against the mirrorless competition is playing it against a stacked deck: it simply can"t win. For me, the Pentax Q just isn"t the right camera, no matter how much I wanted lớn love sầu it. For you, it might be--but only if form size & weight are your top priority.

 

Pentax Q Image Quality

The crops below compare the Pentax Q to lớn a couple of premium Point và Shoots (the Canon G12 and Nikon P7100), and a few Compact System Cameras (Nikon V1, Olympus E-PM1 và Sony NEX-5N). Though we normally start with ISO 1,600 here, we thought we"d start with base ISO khổng lồ show the best each camera can vì.

A note on diffraction limiting: We initially shot the Pentax Q Still Life scene at f/5.6, which produced disappointingly soft images. Shooting it at f/2.8, though, yielded sharper images near the center, though corners were softer. (Selecting an aperture for lab shots is a tradeoff between sharpness, field curvature, depth-of-field, và available shutter tốc độ.) Because the Pentax Q uses a smaller sensor with more pixels than the Canon G12 & Nikon P7100, for example, diffraction limiting sets in at above f/2.8. We shot the G12 & P7100 at f/5.6, but the same calculations show the lens lớn be diffraction limited at that setting; the cameras may look slightly sharper at f/4. Of course, we can"t determine that without re-obtaining the cameras in question & re-shooting them, which we don"t have the time lớn vị. Just bear these factors in mind when looking at the images below.

cảnh báo also that these images are best quality JPEGs straight out of the camera, at default settings including noise reduction. Each camera was shot with the sharpest lens on hvà, though we have sầu no reference lens for the Pentax Q system yet, so we had lớn use the Pentax 8.5mm f/1.9 Standard Prime for it. The point-and-shoot cameras we"ve sầu included here obviously used their fixed zoom lenses.

Our initial chạy thử images with the Pentax Q were noticeably softer than this, taken at f/5.6 with the 8.5mm Standard Prime. Changing to f/2.8 yielded better results, though we have sầu no way of telling whether the G12, shot at f/5.6, would do significantly better at f/2.8. That significant variable told, the 12-megapixel Pentax Q does fairly well, better than the 10-megapixel G12 on the mosaic label, but not quite as good on the red leaf swatch.

Also up against the 10-megapixel Nikon P7100, the 12-megapixel Pentax Q does a little better with the olive oil bottle shot và mosaic image, but not quite as good at the red leaf swatch. Pentax"s rendering of the pink swatch is also decidedly more magenta.

Though its sensor is even larger than the Nikon P7100, the 10-megapx Nikon V1"s results are similar, with lower performance in fine detail, but better performance in the red leaf swatch when compared lớn the Pentax Q; and that"s exactly what we"d expect given the Pentax Q"s smaller sensor kích thước at a higher resolution.

Pentax Q versus Olympus E-PM1 at base ISO

*
*

Finally finding a match in resolution against the 12-megapixel Olympus E-PM1, the Pentax Q fares surprisingly well. (Bear in mind that the E-PM1 was shot at f/8, yet with a very sharp lens.) The Olympus show more sharpening, but also more detail, especially in the pink swatch, where one can see the gaps between threads. It"s a pretty cchiến bại competition, one in which the Pentax Q does better than expected.

Pentax Q versus Sony NEX-5N at base ISO

*
*
*

The 16-megapixel Sony NEX-5N (shot at f/8) shows what can be done with our still life target, standing as one of the highest quality compact system cameras available for the money. Still, there"s more evidence of sharpening halos in the Mas Portel bottle (top) than in the Pentax Q image. There"s more detail in all the other elements, though, including the mosaic image, the red leaf swatch, and the pink fabric. Given its APS-C sensor kích thước và higher resolution, though, it"s no surprise that the Q couldn"t quite rise to lớn the challenge.

Most decent cameras produce very good results at base ISO, so we like lớn see what they can vì at higher settings. Recent advances in sensor công nghệ have made ISO 1,600 look a lot more like ISO 100, but there still are cameras whose quality starts to lớn fall apart at this setting. We also choose 1,600 because we lượt thích to lớn be able lớn shoot at least at this level when indoors & at night.

Pentax Q versus Canon G12 at ISO 1,600

We argued pretty heavily at its introduction that the Pentax Q"s primary competition was the G12 & P7100, not other compact system cameras with larger sensors. So the above sầu results are instructive sầu. The Q does slightly better with the Mosaic image, but the rest is pretty equally soft. Contrast và color are better from the Q, though, và the Mas Portel label at the top does look a little better. Still, both cameras struggle a lot at our first benchmark ISO 1,600 chạy thử.

Color is again the differentiator between the Pentax Q và P7100, & the Q also retains more high-contrast detail than the P7100.

Despite its larger sensor, the Nikon V1 doesn"t bởi vì as well against the Q as we"d expected. It"s pretty close khổng lồ a draw, with slightly richer color from the V1, but also more blotchy chroma noise, particularly around the olive sầu oil bottle.

The Olympus E-PM1 resolves a bit more high-contrast detail, & does a lot more processing on the image. It may look a little more artificial onscreen, but it results in a larger print.

Few words are required to show the differences here. The advantage lớn a larger sensor could be illustrated clearly with these crops.

Today"s ISO 3,200 is yesterday"s ISO 1,600 (well, almost), so below are the same crops at ISO 3,200.

There"s surprisingly lower image quality in the Canon G12 images, with more blotchy noise & less color retention than the Pentax Q manages. lưu ý that the Pentax Q"s aperture was f/4 at ISO 3,200, because of the 1/2000 second shutter tốc độ limit.

The Nikon P7100 fares far worse at ISO 3,200 with both blotchy luminance noise & noticeable color loss. We prefer the Pentax Q"s output.

The Nikon V1 retains more detail & color than the Pentax, showing a better sense of all elements, including the mosaic và even the red leaf swatch, a different outcome from the ISO 1,600 results, where the Pentax Q seemed lớn have sầu an edge.

Detail comparison. High-contrast details are often sharper as ISO rises, so they"re worth a look as well. The Pentax Q"s detail is superior khổng lồ the 10-megapx contenders in this test, but only just enough for color demosaicing errors to lớn appear in the fine lines in our Pure Brewed label letters, a fairly comtháng error aý muốn Pentax sensors in particular. As ISO rises, detail blurs more dramatically, though the aperture of f/4 at ISO 3,200 & f/5.6 at 6,400 contributes to the softness. Still, it"s easy to lớn see that the larger sensors in this comparison bởi better by default at higher ISOs.

 

Pentax Q Print Quality

Great 16x20-inch images from ISO 125-400; ISO 1,600 makes a good 8x10; ISO 6,400 shots are a little too soft at 4x6.

*
Diffraction limiting affected the Pentax Q so dramatically that we had khổng lồ reshoot our Still life shots at f/2.8 to lớn get a sharper image, because the Q"s original print quality assessment showed a disappointing 11x14-inch maximum print kích cỡ for images shot at f/5.6. The new prints show considerably better performance.

ISO 125 shots look quite good in the detail department when printed as large as 16xtrăng tròn inches. Unsurprisingly, reds are a little soft at this kích thước, but we think most folks would accept the output as quite good.

ISO 200 images are also very good at 16xđôi mươi inches.

ISO 400 images are good at 13x19, but the red detail is a little softer, such that we prefer it printed at 11x14 inches.

ISO 800 shots look very good at 11x14.

ISO 1,600 shots are quite good at 8x10. Reds are soft, but that"s not surprising for the sensor kích cỡ. What"s surprising is the good chất lượng 8x10 at ISO 1,600!

ISO 3,200 images appear a little smudgy at 5x7; the color is there, but the detail seems too soft. Reduction to lớn 4x6 results in a more normal-looking print.

ISO 6,400 images have the color, but not the detail again. The laông chồng of noise is pretty remarkable, but it comes at the cost of detail. We"d điện thoại tư vấn it usable, but not stellar.

Overall, though, the Pentax Q shot at f/2.8 performs very well, redeeming itself somewhat in our eyes from our first impressions. Diffraction limiting makes smaller apertures less useful for sharp images, but that"s just a fact of digital photography, especially with small, high-resolution sensors.
