It was aimed at demanding amateur and semi-professional photographers. The SR-T stayed in production for ten years with only minor changes. The design is based on the Minolta SR-7 model V camera of , but the principal design is inherited from the original Minolta SR The most significant one is perhaps the full aperture metering facility, allowing the exposure to be set accurately without stopping down. Another unique feature of the SR-T besides the open aperture metering at the time of its release to the public at Photokina in was the so called "CLC"-metering characteristic. Therefor the metering system always detects an average of the light travelling through the lens, determined by the contrast division of the metered motive.

Sales began in April and it stayed in production with only minor changes for ten years, the result of the thorough development effort that was put into the camera. The body is a direct continuation of the Minolta SR-7 model V of , itself an innovative camera. Perhaps the most notable new feature was the full aperture metering facility, a feature it took Nikon twelve more years to figure out how to accomplish.
For a time, Minolta dominated this area of camera design. SR mount lenses are generally usable in unmetered-manual mode on MC mount cameras, but some automatic-diaphragm lenses made before have compatibility issues with the diaphragm coupling. MD lenses made later add a second tab to signal X-series cameras that shutter-speed priority is available, and these lenses are backwards-compatible with the MC cameras such as the SR-T series.
The first generation camera body serial numbers started from xxx see section below. A very well crafted ever-ready case was available in either brown or black leather to protect the camera with normal lens. The SR-T series subsequently included many models, all of them variations on this body. Most of these were budget models lacking some of the special features of the top-range SR-T models; many of them lack the shutter-speed indicator, for instance.
The SR-T is a somewhat blocky camera by modern standards, but it represents a school of industrial design that was ahead of its time in the mid's. The film advance can be operated in one strokes or multiple, whichever is more convenient. The lever goes quite far forward when operated in one stroke. Other controls are on the sides of the lens mount; on the earlier SR-T 's, these controls are a depth of field preview button which stops down the aperture this locks in place on the SR-T but not on some later models and a mirror lock-up knob, mainly provided to make the camera compatible with ultra-wide angle lenses.
The lens release is on the front of the lens mount; it is a knurled knob that must be pushed diagonally towards the lens to release it. Around the lens mount is a spring-loaded ring that travels with a stud on the aperture ring or a stud linked to the aperture ring, in the case of some longer lenses where the aperture ring is not adjacent to the camera.
This tells the camera how many stops below the maximum aperture the lens is set to, and allows the camera to meter at maximum aperture. The camera lacks the mechanical provision to double-expose by holding the rewind release and cocking the shutter, but later models would add this feature.
It may be possible to double-expose by pressing and holding the rewind release and holding the rewind knob, but it seems this is exceedingly difficult to do without moving the film somewhat, and would likely take two people to accomplish with ease and accuracy.
The shutter, like the aperture-sensing ring, is connected to the follower needle in the viewfinder, not as in some match-needle cameras, the meter needle itself. It is also connected to a sliding bracket in the lower part of the viewfinder that indicates the current shutter speed. There is a self-timer, of the same kind as on the Pentax Spotmatic , for instance.
It is a lever which is wound up by hand and released by a small button above it. The SR-T has an extremely bright finder, owing to its large, double-hinged mirror.
The ground glass has a central micro prism focusing aid that proves to be very accurate in most cases, since even when no visible lines are present in the subject, all out-of-focus objects appear to shimmer.
Some later models replace this with a microprism ring around a split-image device. The meter and follower needles are shown at the right and the selected shutter speed is at the bottom. A small rectangle by the needles indicates the battery charge; if the meter needle is somewhere over this rectangle when the switch is set to BC Battery Check , the battery is in the acceptable range.
This bright, feature-packed viewfinder would prove to be a high point of Minolta SLR's, and the SR-T series would preserve the bright finder throughout; some, such as the SR-T Super sold in North America as the would add a "Judas window" above the image to show the current aperture though it would not work with all lenses or in dim light. If there is high contrast between the two, it compensates by assuming that the upper side of the picture is the sky and that the lower part is the subject you want to photograph.
ISO values can be set from 6 to The meter is the only battery-powered component; it takes an obsolete PX mercury battery, banned in most countries other than Russia, but workable alternatives are readily available. The SR-T 's viewfinder shows the exposure meter needle at the right side of the finder image. This needle shows the actual light value coming in through the lens at maximum aperture, with lower indicating a higher light value. The needle's position is not dependent on film speed or any other camera setting; it will be constant for a given light value and a given lens.
Also at the right is a follower needle with a circle at the tip. This indicates the current exposure value calculated from film speed, number of stops below maximum aperture, and shutter speed. By changing one or more of these inputs, this circle can be made to overlap the meter needle, at which point the exposure will be approximately correct. The second image shows the meter in battery control mode: needle over the little rectangle means correct voltage. This was possible thanks to the fact that Minolta had placed the aperture ring on its Rokkor MC lenses close to the camera body.
This way, the position of the aperture ring could be communicated mechanically to the metering system inside the camera. What is actually transmitted is not the aperture itself, but the offset between the selected aperture and the lens' maximal aperture.
Several internal parts may fail on a forty-year-old camera, and the SR-T is no exception. The most serious trouble is related to the exposure meter movement, in which the tiny coil can break; this situation requires a replacement. The back door rubber sealing foam will usually need replacement, and so will a small strip of same cushioning the mirror when it goes up. A strip of this may be cut from a similar sealing material from a hardware store.
Many other problems can be solved by removing the top which is somewhat difficult and putting right the strings and pulleys that communicate aperture and shutter speeds. During the ten-year manufacturing period of the Minolta SR-T, many small changes were made to the camera body. Several of these changes are easily detected and they can help determine time of manufacture to within a few years. It should be noted that any part of a camera may be replaced due to repair and smaller parts are more easily swapped, but normally these features may be considered original.
Top cover and base plate are parts usually replaced due to impact damages, and a replacement top cover would not have the original serial number. From on, the black plastic shoulder pieces between the front cover and the top cover are held in place by visible screws. In Fall Minolta began selling black body SR-T's, like image at left, from serial number xxx on. From on, as seen on the inside of the top cover, the film counter clear plastic window is glued in place, while on earlier versions it is held in place by an internal bracket.
This would be the design used when the shoe was replaced with a hot shoe on later models. MLU first began to be discontinued early in the transition to the second generation, but did continue at least until the third generation SR-T. The Sr-T began a long-lived, commercially-successful and lauded series consisting of incremental upgrades of this body, as well as affordable budget models lacking some features. The most common variation, sold under various model numbers, removes the mechanically-complicated shutter-speed indicator and the self-timer; variants with and without hot shoe and even a variation with single-cell non-CLC metering exist within this budget range.
The SR-T Super sold as SR-T and its successors would add a Judas window for the aperture ring, thus showing all the exposure information in the viewfinder. Some models, such as the super add a split-image device, and some models were made with either focusing screen.

Questions About Minolta SRT-102! Help please!
Help please! I know pretty much close to nothing about this camera except for what I could find online on other forums and the manual and stuff but I was wondering if anyone could tell me some key things? As in, I tried out how to use the multiple exposure feature but I'm not sure if I used it right? I know I only need it for the internal meter but I don't really even know what that means.
Minolta SR-T 102 Manual
Just got it for my birthday last week. It didn't come with a manual so I was wondering if anyone has one I can buy or knows where I can get one. Also I cannot figure out how to open the film door to put the film in. Anyone know how? Go to butkus and download one. Also to open the film door you pull up on the film rewind knob.
For the first time Minolta had released a camera with through the lens metering, but unlike its competitors it did this at full aperture. Where other manufacturers were struggling with systems where the photographer would have to stop the lens down to check the metering, the Minolta SR-T enabled metering to be conducted with the lens wide open. This meant that the meter reading in the viewfinder was always clear and bright, and that the photographic process could be more about inspiration, not perspiration. To support this system an entire new range of lenses were introduced, the "MC" line for "meter coupled".
