The Canon TLb is a 35 mm single-lens reflex camera introduced in the Americas by Canon in September 1974 and discontinued in 1976. It features a Canon FD lens mount, and is also compatible with Canon's earlier FL-mount lenses in stop-down metering mode. The TLb was a cheaper version of the Canon FTb for the export market, as was the slightly later TX. Compared to the TX, the hot shoe was omitted, although the camera included a PC terminal for flash sync and with a maximum shutter speed of 1/500s in place of the FTb's 1/1000s. It has TTL metering using a CdS cell, powered by a 1.35V HD mercury battery. The TLb was later (April 1976) sold in Japan. The shutter is a two-axis, horizontal-travel focal-plane shutter with cloth curtains. The speeds are X, B, 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500 of a second with no self-timer. The film speed range is ISO 25 to 2000 and film frame counter ends at 40. The camera was known as the Canon TLb in America, Japan, Europe, Asia, and Oceania. The camera also has a fold down rewind crank handle that when pulled up releases the back cover, thumb lever single action film advance, fixed eye-level pentaprism viewfinder, rewind release button, and two hard points for a strap.
