To distinguish it from the other SLRs, it had shutter priority auto exposure. As I understand it, this is the first SLR with autoexposure. Canon introduced a shutter priority SLR in October 1969 with the EXEE but that had a dedicated screw mount with only interchangeable front lens element. The Pentax ES aperture priority SLR didn't get released until 1971.
