Canon FT
Pulled out the old Canon FT (1966). The FT was the last in the line for FL (breach lock) lenses for Canon before moving to FD lenses. The FT series was, in effect, the last of the consumer mechanical SLRs before Canon introduced the revolutionary AE-1 electronic camera. The FD lenses will work on the FT, but you must take the lens out of "auto" and manually push the meter lever to meter in "stop-down" mode. This is welcome for me, as the viewfinder will darken if a small aperture is set and you can see what's in or out of focus. The downside is actually seeing the match-needle if it's in dim light.. This "depth-of'-field" check is on many cameras. The FTb camera that followed, along with the FD lenses, eliminated the necessity to "stop-down" meter.
