Canon TLb

Canon's TLb is a 35mm SLR which updated their entry-level TL by adding open-aperture metering. This is accomplished by adopting the FD lens mount which had been introduced with the launch of the the F-1. (In the same way that the midrange Canon FT had been updated as the FTb.) Older FL-mount lenses can be used with stopdown metering. The TLb was introduced to the US market in 1972, and sold in Japan from 1976.
