is a 35mm SLR
with a focal plane
shutter, introduced in 1974 overseas, and sold in Japan from 1976. Like the Canon TX
(which it pre-dates), this was a budget model, based on Canon's FTb
. In addition to the features omitted in the TX, the TLb also lacked a hot shoe
The TLb has TTL metering using a CdS cell, powered by a mercury battery.
