The FT can also operate the later Canon FD series lenses in stop-down mode, but the earlier R series has a different lens aperture mechanism and cannot be used, although the bayonet fitting is similar.The standard kit lenses were Canons 50mm f1.8; 50mm f1.4 and 58mm f1.2, the body-only option was offered later.However it differs from the Pellix models, having a normal quick-return reflex mirror and offering stop-down TTL metering.The TTL metering is semi-spot in nature and works through a prism incorporated in the viewfinder condenserscreen assembly.
Canon A1 Year Series Lenses InThe later Canon F-1 has a similar prism for metering in its removable screen. The pentaprism finder is fixed like the similar FX and FP models but unlike some earlier Canon R reflexes. The mirror can be locked up for vibration reduction or for use with special FL lenses like the original 19mm f3.5 wide angle which projects deeply into the body and would foul the mirror. A stainless steel sprung hinged device inside the rear door makes film loading simpler than competing cameras of the era. It is a plug-in device that sits on the accessory shoe and increases the metering sensitivity by a factor of 16 for measuring exposure in poor light. Its operation is somewhat clumsy and is best kept for tripod use. The first was the Canon FX which had a built-in meter, but no through-the-lens (TTL) metering, instead using a window on the camera body front. The final model was the top of this sector, the Canon FT QL, which was developed to combat the growing popularity of the Pentax Spotmatic variants as well as the Topcon RE SLRs.
