The 137MD was the third camera produced for Contax by Yashica, and it was the first and at the time the world's smallest integrated motor drive camera body. The motor drive could run at the rate of 2 fames per second. It offered an aperture preferred automatic mode and an AE lock, but no manual mode; this was cured by the introduction of the 137MA 2 years later. This camera was only 3mm taller than the RTS, which astonished the press at the time, since it was motor driven. Film rewinding was still manual with a rewind crank, which I prefer anyway, since it lets me leave the film leader out when I wish. It also had an exposure compensation dial. There were two other cameras on the market at that time that were automatic only; they were the Nikon EM and Canon AV-1. One unusual feature of this camera and the 137MA is that as long as the power is turned on, the power LED lights up and the metering is lit up. It doesn't turn off afer some period of time like most others. It uses 4 penlight batteries and is very easy to turn on an off with the larger than norman power switch, so I have never had a bettery life poblem with it. I like it a lot. It is a great little motor drive camera.
