Canon's budget FD SLR — the TLb, stopped-down CdS metering, cloth shutter, entry-level, 1974.
The Canon TLb, introduced in 1974, was a stripped-down, budget derivative of the FTb within Canon's FD-era range. It aimed at cost-conscious and beginner photographers who wanted an FD-mount SLR with basic TTL metering at a lower price than the FTb, sitting at the entry level of the line.
As a 35mm SLR the TLb used the Canon FD breech-lock bayonet, compatible with FL lenses, and a cloth focal-plane shutter with a range typically to 1/500 plus bulb. It featured through-the-lens CdS metering using a stopped-down match-needle method rather than the FTb's full-aperture system, with manual exposure control. The CdS meter needed a battery, while the mechanical shutter fired without power.
The TLb suits beginners, students and users wanting an inexpensive entry point into the FD system with straightforward manual controls. Its stopped-down metering and reduced top shutter speed keep it simple and affordable, though less convenient than full-aperture bodies. It is a practical learning camera with access to the broad FD lens range.
On the used market, the CdS meter was designed for a 1.35V mercury cell, so account for the discontinued PX625/625 battery when judging accuracy. Test the cloth shutter for capping and accuracy, inspect for perished foam light seals, prism haze or desilvering, and confirm smooth advance and rewind. Verify the stopped-down metering switch works. FD and FL lenses adapt to mirrorless bodies for ongoing use.
