The Autoreflex T, launched in 1968, was a groundbreaking 35mm SLR, being the first to integrate focal plane shutter, auto-exposure, and TTL metering in a single body. Marketed as the FT A in Japan and Revue Autoreflex TTL in Germany, this model dropped the hyphen from its predecessor's name. Operating fully mechanically, it relied on two PX 675 type mercury cells solely for the CdS light meter. With shutter-priority auto-exposure and a range from 1s to 1/1000s, the Autoreflex T was a notable innovation. The Autoreflex W, a specialized variant for sports, featured a timing back imprinting exposure times on each frame.
