Yashica FR I
The Yashica FR I was an electronically-controlled SLR camera, first introduced in 1977. Based on the earlier Contax RTS and Yashica FR, the FR I combined some of the best attributes of those cameras. Equipped with the C/Y common bayonet mount, the FR I could accept a variety of Contax/Yashica lenses and was targeted at serious amateur and professional photographers who did not need the added features of the more expensive Contax RTS. It had an electronically-controlled shutter with speeds from 1 sec. to 1/1000 (plus B), two exposure modes - manual and aperture priority - as well as DOF preview, self-timer, and full exposure information visible in the viewfinder. Production ended in late 1981.
