SRT102


(1973)   The SRT101 was amazingly convenient for a manual-exposure camera -- but still, it lacked some important convenience features.  An improved version of the SRT101 came out seven years after the introduction of the SRT101 -- the SRT102.  In this model, in addition to the shutter speed, the f-stop is displayed in the viewfinder. Now there is no need to ever take your eye away from the viewfinder while taking a picture.  The SRT102 also has multiple exposure capability and a built-in hot shoe. Last, but not least, a split-image rangefinder was added to the middle of the microprism circle of the focusing screen. There were a few other differences as well.

Although the body of the SRT102 looks, at first glance, exactly like that of the SRT101, there are some subtle differences.  The SRT101 used the "B-style" body with a thin ridge along the top front and rear edge (below left).  The SRT102 used a new body design ("C-style") that removed the ridge (below right).  Many people don't even notice the difference until it is pointed out, but some people feel that the SRT102 has a cleaner look.

The SRT102 also has a pentaprism that sticks out further than that of the SRT101 and SRT100.  There is a new plate on the front of the pentaprism with a tiny window on the bottom that allows the f-stop to be displayed in the viewfinder.  This same approach had been used in the XK of 1972 and was adapted to the SRT102.  The f-stop display works best with MC ROKKOR-X and later lenses, but most earlier lenses will function adequately.

Another change for the SRT102 was in the PC contacts.  On the SRT101 there are two contacts on the side of the lens mount -- one for FP (flash bulbs) and one for X (electronic flash) connections.  On the SRT102, this design has changed.  The upper connection remains, but it now used for both the FP and the X connections.  The lower contact is replaced with a switch to select either FP or X. In addition, the SRT102, added a convenient multiple exposure capability. Lastly, there is a minor change in the flash shoe.  Not only is the SRT102 shoe hot, but the front plate of the shoe is a black plastic plate instead of a metal tab on the SRT101.  

There were actually several versions of the SRT102, which depended on where and when you bought the camera.  The model is not inscribed on the cameras.

Unfortunately, the SRT102 was only manufactured from 1973 to 1975, so it is the least common of the major SRT100 series cameras. Since the shutter will operate without a battery, it is built like a tank, has complete viewfinder information, and has a mirror lock-up device, many consider the SRT102 (model a) to be the best manual-exposure camera ever made -- by any manufacturer!  And it often sells for less than the SRT101.  The SRT102 (model b) was replaced with the SRT202 of 1975.  For a comparative look at the major features of the SRT102 models, check out MINMAN's SLR table -- the world's most complete!
