Minolta srt 101 đánh giá

A recent re-associating with the Pentax Spotmatic F had me pondering about some of the other ‘Golden Oldies’ that have been sitting by the skirting board in my living room for a number of years. Often as not a new purchase would actually be an exercise in stripping down & putting baông xã together. A number of these cameras were Minolta SRT 101s.

Minolta’s SR line began baông xã with the SR-2 in 1958 – this was an unmetered camera which operated a new bayonet mount – one that would only go out of production with Minolta in 1999.The SR bayonet (often mislabelled as MC or MD) was quite versatile – it allowed open aperture viewing và, when the SRT 101 came around in 1966, lenses designated as Meter Coupled (MC) could also meter wide open, with the camera able to detect what aperture the lens was phối to lớn. Later incarnations even allowed for multi-mode metering. The one thing they didn’t adapt it khổng lồ do was autofocus and Minolta switched to a new mount for that in 1985. The SR mount still continued however with the x-700 ending up as one of the most produced manual focus SLRs of all – still bearing the SR mount.

The lenses

The lenses on SR-vintage cameras generally bore the name Rokkor, although some later lenses may just be branded Minolta.

The range of Rokkors is extensive sầu, through from 7.5 mm fish-eye lenses lớn 1600mm mirror lenses, 600milimet refractive sầu lenses, Macros, Variable soft focus lenses, Variable curvature lenses, shift lenses & superfast f/1.2 standards. Minolta may never have broken into lớn the professional ranks in the same way as Canon và Nikon, but it wasn’t for want of ‘class glass’. Rokkor lenses are very highly regarded.Minolta specialised in coatings và improved them throughout production. At the same time there was a move over time khổng lồ reduce cost and weight, so build unique might be perceived to lớn be less ‘cast-iron’ on later models. I have always held that there is no such thing as a bad lens – rather, some lenses may have sầu character that is harder khổng lồ fully exploit… In any case, if it says Rokkor or Minolta on the front, it is likely lớn be a nice (or at least interesting) lens.

The SRT series

There were a whole series of SRT bodies, varying subtly in features. The first was the Minolta SRT 101 which carried on in production (with slight name changes) for 15 years as recognizably the same camera. The copy I’m reviewing is an SRT 101 from the early 70s.The big thing with the Minolta SRT 101 was the full aperture TTL metering – it was also rather clever, using a mix of CdS cells in an exposure formula that Minolta dubbed Contrast Light Compensation (CLC). This worked very well and effectively meant that the camera was not over-influenced by very bright sources of light within the viewfinder – it tried to expose for shadows rather than highlights that were likely to lớn blow out in any case (such as street lamps or the sun).The specification is very good. In addition to lớn the open aperture metering và the mirror lockup, the Minolta SRT 101 has a self timer, locking depth of field switch (click to lớn loông chồng, clichồng again or take a shot khổng lồ unlock), a battery check & meter switch và a viewfinder that shows you shutter speeds, allows you to set exposure by matching a ‘paddle’ to lớn the meter needle & gives you a microprism focusing aid.

A voyage round my Minolta SRT 101

Top plate

The Minolta SRT 101 carried on with the same top-plate layout that had been used by Minolta for SLRs since the SR-2 of 1958. This layout seems lớn have sầu been inspired by the Leica M3 which has a similar arrangement of a shutter release within the hub of the wind-on lever.

Underneath

On the base of the Minolta SRT 101 is a centrally positioned tripod mount, a battery chamber, an inmix rewind button and (unusually) a meter switch. This is not the best ever position for a meter switch và it has to lớn be operated by pressing a finger against the flat rotary switch and twisting. It works, but it is easy lớn forget khổng lồ switch the meter off. The switch also includes a ‘BC’ position which deflects the needle in the viewfinder lớn a reference point khổng lồ confirm that the battery is still good. Unusually (again that word!) the battery chamber cap is not slotted for a coin – instead it is knurled & relies on the pressure of a fingertip while rotating (notoàn thân ever liked their finger tips anyway did they?)

The Viewfinder

The viewfinder of the Minolta SRT 101 gives a fair amount of information. It shows the selected shutter speed at the bottom of the viewfinder, và a needle from the meter on the right, this is matched against a paddle (a circle on an arm) the position of which is affected by both the aperture & shutter tốc độ mix. In order to vì chưng this the camera needs lớn transmit a fair amount of information from the shutter speed dial (where both shutter speed & ASA value are set), over lớn the opposite side of the pentaprism, which is where the meter sits.While the meter stuff can be done by wiring, the position of the shutter tốc độ dial has to be physically transmitted. I was amazed the first time I had one of these Minolta SRT 101s apart to lớn see the little cables & pulleys that achieve articulation of the metering paddle. It says much for chất lượng control that anything that old (and the oldest of them are over half a century old) can still be functioning.

101 variations

Over time

The early Minolta SRT 101s had a ‘cold shoe’ & a mirror lockup. It would seem that the mirror lockup was mainly to lớn accommodate a 21milimet super-wide non-retrofocal lens where the rear elements would have interfered with the camera’s (large) mirror, but of course, it was also useful for microscopy và astrophotography. The introduction of later retro-focus wides may (along with cost-cutting) explain the disappearance of the mirror lock-up sometime in the early 70s.The earliest Minolta SRT 101s use slot head screws for the top & bottom plates và have sầu a black finely knurled shutter tốc độ dial. My SRT 101 is from the second generation (1970-1973), which used cross head screws and had a more coarsely knurled chrome shutter speed dial. It is this series that lost the mirror lockup at some time during production, although my copy still has it.A reasonably significant change occurred in the late 70s when the camera got a ‘b’ suffix in Europe & a slight name change in other regions (201 in North America & SR101b in Asia/Pacific) – this updated version gets a more conventional depth of field preview button (press & hold, rather than toggle on và off) and lost the CSC metering. This would appear to lớn have been an economy measure, as the CSC system required two CdS cells in different positions, while the ‘b’ used a single cell. The ‘b’ did get a brighter focusing screen though, with a split-image rangefinder in addition to lớn the microprism.

Other variants

The same basic body toàn thân was used for cheaper and more expensive sầu variants – one was the first ever SLR with an integral motor drive sầu – the SRM. This could buzz along at 3 frames per second, but lacked TTL metering. A budget Model, called SRT 100 shaved the costs by losing the top shutter tốc độ (maxing out at 1/500) và the shutter speeds in the viewfinder.In addition khổng lồ paring away, Minolta introduced a higher-specification mã sản phẩm, which had different names in different markets – 102 in North America, ‘Super’ in Asia-Pacific và 303 in Europe. The Minolta SRT 101 spec was already quite impressive, but the 102/Super/303 added a hot shoe, Full information viewfinder, with lens aperture being read via an Aperture Direct Window at the front of the pentaprism, a split image rangefinder to lớn go with the microprism and a fool-proof method of getting properly registered deliberate double exposures. A slightly revised version was released in 1976 – this kept the CSC metering but adapted the ‘press & hold’ operation for the depth of field pReviews. The new version was called 202 in North America, 505s in Asia/Pacific and 303b in Europe.In addition khổng lồ the above, there were special editions produced for certain department stores, which tended to be lie somewhere between the 100 & the 101 for specifications. The SC was sold through Sears, while the MC was sold through K-Mart.For more information, look up the (very excellent) Rokkor Files – a wonderfully useful web resource for anyone interested in SR mount cameras & lenses.
