Canon got off to the slowest start of the original Big 4 Japanese camera makers (Minolta, Nikon, & Asahi Pentax were the others) when it came to SLR development and sales . This was partially due to their commitment to interchangeable lens rangefinders for longer than their competitors. By the mid-1960s, however, they had embarked on a slow but steady climb that would lead them to market dominance by the late-1970s. Their first truly competitive SLR was the FT of 1966, and it would spawn one of the finest series of mechanical-shuttered enthusiast SLRs of the age and Canon's most successful non-A-series manual focus model. The second- and third-iteration FTb & FTb-N would prove to be the backbone of Canon's amateur lineup in the first half of the '70s and sold extremely well while both Pentax and Minolta were facing declining sales of their excellent Spotmatic & SRT mechanical SLRs at that time. That alone makes it a pivotal model in Canon's history. But it is much more than a sales footnote, it was one of the best enthusiast-level SLRs of its day, and that makes it a great choice today for the film-SLR aficionado. You could call the FT the analog 5D of its era :-).
Suffers from a two-decade and counting film and manual focus SLR addiction. Has recently expanded into 1980's AF point and shoots, and (gack!) '90s SLRs. He even mixes in some digital. Definitely a sick man.
