That depends. Just as there were TWO versions of the SRT102, there were TWO versions of the SRT202.
The first model of the SRT202 was almost the same as its predecessor, the
SRT102 (model b), but it had the addition of a film tab holder on the back (the new film memo holder retains the ASA/DIN converter, but you can't see it if you have a film tab inserted) and a film advance window. Nice touches, but Minolta dropped the mirror lock-up feature. Two steps forward, one step back. The viewfinder and focusing screen remained the same.
But there were subtle differences as well. The previous model had "MINOLTA CAMERA CO.,LTD." imprinted on the top between the pentaprism and the rewind crank. On this model, the imprint is gone. In addition, the film plane indicator, which had been behind the shutter speed dial (on the right), is now placed between the pentaprism and the rewind crank (on the left). This was a smart move and makes measurements a little easier for those few people who use it. Last, the hot shot on this model is marked with a red "X", hopefully to remind users that the "hot" part of the shoe is only usable with X-synch, not bulbs.
In 1977, a few changes were made to the SRT202 (model a). This was the same year that Minolta introduced the first of the XD and XG cameras, and several of these features were copied directly from the XD and XG line. Perhaps it was an attempt to make the older-styled cameras look as similar as possible to the newer cameras, but it is just as likely that the newer parts were available -- and usable -- on the older cameras. First, there was a switch on the SRT202 (model b) to a black, plastic aperture ring around the lens mount -- replacing an aluminum ring.
In addition, the locking DOF button of the earlier SRT cameras was replaced with a non-locking DOF button. On the surface, this sounds like a minor cosmetic change. But the change is more than skin deep. At the same time, Minolta dropped the "meter off" switch which, in all previous SRT models, would automatically turn the meter off when the DOF button was pressed (when an MC lens was attached to the camera). The purpose of this early feature was to allow metering in "stop-down" mode with early non-MC lenses. That's why the DOF button on Minolta SLR cameras was originally called the "stop-down-metering" button. So with this switch, Minolta was cutting out a few cents in manufacturing costs -- and casting aside users of earlier lenses.
Also, the SRT202 (model b) only had X synchronization for flash use -- the FP option of the SRT202 (model a) was dropped. Look for the black, plastic aperture ring around the lens mount to identify the SRT202 (model b).
