The Canon FTb is a 35 mm single-lens reflex camera manufactured by Canon of Japan from March 1971 replacing the Canon FT QL. It features a Canon FD lens mount, and is also compatible with Canon's earlier FL-mount lenses in stop-down metering mode. Launched alongside the top-of-the-line F-1, the FTb was the mass-market camera in the range.[1]

The FTb was primarily intended to be a camera for the advanced amateur photographer, offering many of the same features and same build quality as the F-1, but without the option of interchangeable prisms, focusing screens, or motor drives. The Canon FTb was released at a retail price of 35,000 yen for the camera body ($99 USD; or $580 in 2014 USD).

The FTb has an all-mechanical horizontally traveling focal plane shutter with timed speeds from 1/1000 to 1 second and bulb. The FTb has rubberized silk shutter curtains rather than the more durable but more expensive titanium curtains found on the F-1.

It offers a 10 second self-timer, as well as mirror lock-up.

The meter is of the 12% (1/9) partial type with the metering area indicated by a slightly darkened box in the center of the finder area. It is fully coupled to shutter speed dial and aperture ring on FD lenses in the match needle style. The meter was designed to be powered by a single 1.35 volt 625 Mercury cell, which is no longer available. Popular options for replacement are to use a higher voltage silver battery either through a voltage dropping adapter or recalibrating the meter, or using zinc air batteries, which have the same voltage but a relatively short life.

In 1973, the FTb design was revised slightly. The camera was given a plastic tipped film advance lever. The stop down lever was changed to the same style as that found on the F-1. The PC sync socket was given a spring-loaded plastic cover. The ring around the outer edge of the shutter speed dial was changed from a scalloped design to a diamond textured design. Finally, a shutter speed display was added in the lower left hand corner of the viewfinder. This model was unofficially known as FTb-N or FTbn.
