Contax ST Specifications Page*
The Contax ST is a fine camera, as far as design and function. It has an MM mount for data bus with all the MM lenses. It is only lacking the vacuum pressure plate and the 5fps shutter speed of the RTSIII. The big design flaw is the power source being AAA instead of the RTSIII that runs on either lithium, or AA.
