With improved technical performance & a refined camera body, the DIGIC 7-equipped Canon G7X Mark II takes advantage of its mostly good built-in 24-100mm equivalent f/1.8-2.8 lens and very good 20.1-megapx 1"-type sensor lớn deliver solid results. Addressing many of the shortcomings of its predecessor, the G7X II is a good compact camera that offers a lot of performance for the price.

Canon G7X II toàn thân is improved và more comfortable khổng lồ use

Among mỏi the changes made for the Canon G7X Mark II are some excellent improvements made to lớn the camera body itself. While the general khung factor is basically the same, there is now a rubber grip on the front, which we found made the camera more comfortable và easier to lớn hold considering its overall compact size.

Despite the lens itself being the same, the Canon G7X II now includes a switch next to it that lets the user toggle between smooth and stepped rotation of the control ring. The new stepped rotation option is nice when controlling aperture, for example, as it allows for quicker adjustments with tactile feedbaông xã.


The 3-inch touchscreen display keeps the same resolution as the predecessor & overall tilting thiết kế, but it can now also tilt downwards lớn 45 degrees. Other than that, the body toàn thân is essentially unchanged. Unfortunately, the Canon G7X Mark II still lacks a built-in viewfinder và doesn"t include a hot shoe so there"s no way to attach an external one (or a flash, for that matter).

Built-in 4.2x zoom lens provides mixed results

Featuring the same 24-100milimet equivalent f/1.8-2.8 lens as its predecessor, the Canon G7X II delivers similarly mixed performance. The 4.2x zoom lens provides more range than most other cameras in its class, but it comes at a cost. Far field performance is good across the board, particularly around f/5.6 where the lens is very sharp, albeit with slightly soft corners. However, wide angle performance leads khổng lồ severe distortion when using RAW images (heavy distortion correction is applied in-camera to lớn JPEG files) và thus corners are quite soft at wide angle. Despite some shortcomings with the lens, we did find it lớn be capable for the most part, and it offers svào telepholớn performance.

The G7X II"s 20MPhường 1"-type sensor captures good images

Like the lens, the Canon G7X II"s sensor is unchanged, though it"s now paired with a faster DIGIC 7 image processor. The PowerShot G7X II captures very detailed images, especially when using RAW files. (The G7X II now also includes the ability to perform in-camera RAW processing, something missing on the original.) Regarding resolution, images are fairly crisp, & JPEGs are sharper at default settings than those from the G7X, although there are sharpening artifacts on high-contrast subjects. Noise suppression on lower contrast subjects limits some fine detail, but the resulting images are still quite good overall.

The G7X II is the first PowerShot camera to lớn include the "Fine Detail" Picture Style premix that was introduced in the 5DS/R DSLRs. The premix allows you to fine-tune sharpness settings including strength, fineness and threshold parameters. The resulting image is more natural-looking and has fewer sharpening artifacts than the mặc định settings. To get the most out of the sensor, though, RAW images converted using good software can produce sharp images with more detail than in-camera JPEGs và fewer artifacts.

Noise performance is very good with the Canon G7X II given its sensor kích thước. Compared lớn its predecessor, the G7X II produced better results at every ISO through 3200. At ISO 125-200 the G7X II produces excellent prints up to lớn 24 x 36 inches. At ISO 400, we still consider it capable of producing a good đôi mươi x 30-inch print. Images captured at ISO 800 show quite a bit more noise so a good print is only possible up khổng lồ 13 x 19 inches. 11 x 14-inch prints are possible at ISO 1600, which is quite impressive sầu for a camera with a 1"-type sensor. ISO 3200 & 6400 images can result in good prints at 8 x 10 & 5 x 7 inches, respectively.

Solid automatic performance makes for a good user experience

Thanks in large part lớn its excellent touchscreen functionality and svào automatic shooting performance, the Canon G7X II proved khổng lồ be an intuitive, easy-to-use camera that still offered enthusiasts the ability lớn take control of all of the camera"s shooting settings.


Excellent touchscreen makes the G7X II fun khổng lồ use

The 3-inch touchscreen display on the Canon G7X II is very good. The camera"s system menus are generally well-organized & can be navigated via touch. In a move sầu that helps compensate for the relative sầu sparsity of physical buttons on the compact body, the Quick Menu is very touch-friendly, as well, and puts many important shooting settings at your fingertips.

Single shot autofocus is dependable, but G7X II struggles with continuous AF somewhat

Utilizing a contrast-detect autofocus system with 31 points, the Canon G7X II provides generally good autofocus performance, and while it"s not the most sophisticated AF system, it proved lớn be dependable in many situations. When shooting stationary subjects, the autofocus was reliable, particularly when using 1-point autofocus & the touchscreen to lớn select your subject. The fully-automatic "AiAF" focus mode was decent, but would occasionally get confused by a busy or a low-contrast scene & fail to lớn lock onlớn the appropriate subject. While specific figures are unavailable, Canon states that the G7X II"s low-contrast autofocus performance and subject tracking are improved compared khổng lồ the original G7X. Continuous autofocus worked well when shooting slowly-moving subjects but struggled to lớn keep up with fast subjects. By selecting your subject using the touchscreen, the G7X II manages to lớn traông xã it fairly well, but your subject needs to lớn be well-isolated. Considering its price point, we found the Canon G7X II"s autofocus performance to lớn be generally impressive sầu.

DIGIC 7 processor gives the G7X II the performance boost it deserves

With its new DIGIC 7 processor, the Canon G7X II is able lớn offer a sizable increase in performance over its predecessor. Other than an inexplicably slower start-up time, the G7X II is faster than the G7X pretty much across the board.

Single-shot cycling times are improved from 0.9 & 1.3 seconds for best chất lượng JPEGs và RAW + JPEG files, respectively, khổng lồ just 0.6 seconds for both image quality settings. Continuous shooting performance has seen a particularly impressive sầu improvement. Whereas the G7X could only record RAW images at 1.2 frames per second, the G7X II can capture 14-bit RAW files (compared to the 12-bit RAW files captured by the G7X) at just over 8fps with locked focus and exposure và at 5.4fps with full autofocus capabilities. JPEG shooting has been improved from 6.6 khổng lồ 8fps, which is still a nice improvement, but not as significant as the RAW shooting improvement.

Buffer depths have been expanded too. We could record 32 JPEG, 21 RAW and 19 RAW+JPEG images before exhausting the buffer. This is dramatically improved from the G7X"s buffer depth of 14, 4 và 2 photos respectively. All in all, the G7X Mark II represents a very significant upgrade over the original camera with regards khổng lồ performance.

100mm equivalent (36.8milimet actual), f/10, 1/200s, ISO 320.While using f/10 introduces some diffraction with a sensor of this form size, the G7X II does include diffraction correction, something its predecessor lacked. Clichồng for original image.
1080p đoạn phim is fine, but 4K đoạn Clip is notably absent

Unfortunately, đoạn phim features haven"t been upgraded with the G7X II, & it is still capped at 1080p resolution at frame rates up lớn 60fps. The laông chồng of 4K video clip recording makes the Canon G7X II fall behind some of its competitors in the video department. You also won"t find any microphone or headphone ports on the camera, but that isn"t too surprising given its class.


Fortunately, Clip itself is generally quite nice with overall pleasing image chất lượng & good autofocus và metering performance. The laông xã of more modern features is disappointing, but if you"re interested in solid 1080p đoạn phim recording capabilities, the G7X II will fit the bill. However, those who place an emphasis on 4K đoạn phim should look elsewhere.

Canon G7X II is a much-improved, very good compact camera

*

Besides the lack of 4K Clip, there aren"t many notable shortcomings of the Canon G7X II. The lens could be better, especially at the wide over, but the 4.2x zoom & compact kích cỡ of both the lens & the camera itself help lớn offphối that disappointment. Its sensor captures sharp, detailed images và offers very good high ISO performance for its class. With its newer processor, the PowerShot G7X II is a much faster camera too, although the continuous autofocus performance still comes up a bit short. Overall, this is a great compact camera that packs a lot of performance for the price. Given that it addresses many of the shortcomings of its predecessor, the Canon G7X Mark II definitely gets a Dave"s Piông chồng this time around.
