The Canon FX, FP and FT QL are a series of three nearly identical 35mm SLR cameras with a quick-return mirror and a mechanical shutter with speeds up to 1/1000 sec. The FX (1964) had a window exposure meter, the cheaper FP (1964) did not have an exposure meter at all, and the FT QL (1966) received TTL stop-down exposure metering. Released in 1968, the TL was a simplified and cheaper version of the FT QL with a maximum shutter speed of 1/500 sec.
The Pellix (1965) and Pellix QL (1966) are cameras with a semitransparent stationary reflex mirror, behind which there was a meterring cell, which raised to perform TTL stop-down exposure metering. About 2/3 of the light from the lens passed directly through to the film, and the remaining 1/3 was reflected to the viewfinder. This design, in addition to providing TTL exposure metering, was simpler, and there was no finder blackout during exposure. However, there were some drawbacks: because of the semitransparent mirror, about 0.5 EV of light was lost, and the viewfinder was 1 3/4 EV darker compared to using a fully reflecting mirror.
The system had an extensive lens lineup: from super wide-angle 19mm to a super fast f/1.2 normal lens, to a super telephoto 1000mm. Included is a 50mm f/3.5 macro lens. Each lens provides the fastest speed for its focal length, with superior definition and resolution. All surfaces of the lenses are Spectra coated, insuring maximum color and tone balance, great light transmission and elimination of glare.
