The Canon FTb was introduced by Canon in March 1971. It is a mid-range mechanical 35mm SLR designed to use the FD-fitting lenses from the Canon F-1 range. In fact it is very similar to Canon FT with the difference the FTb uses FD instead of FL lenses.

The QL badge on the front denoted Canon's Quick Load system; the film was placed across the takeup-spool and the back closed; the film was automatically wound around the spool when the advance lever was operated.

The pentaprism viewfinder features a fresnel matt focus screen with a microprism focus aid. The FTb had open-aperture TTL metering covering an area of 12% in the center of the frame, with a match-needle display in the viewfinder. Metering was powered by a 1.35v mercury battery - now unobtainable, but alternatives are available. Meter film speed range ran from 25 to 2000 ISO.

The self-timer control also acts as a stop-down lever and mirror up function.

The horizontal cloth focal plane shutter has speeds 1s to 1/1000s + B all mechanical, working without battery.

Standard lenses were 55mm f/1.2, 50mm f/1.4 or 50mm f/1.8.

The second version of the FTb released in 1973, known unofficially as the FTbn, had an F-1 style stop-down lever and displayed the selected shutter speed in the viewfinder on a transparent rotating disc. Other cosmetic changes include a plastic tip to the film advance lever, a slightly different shutter speed dial and a permanent cover to the flash connection.
