The Canon AE-1 Program is a killer SLR camera great for anyone who is just getting into film photography or a seasoned photographer looking for a classic camera.
35mm SLR (Single-Lens-Reflex) camera with electronically controlled AE (Automatic Exposure) and focal plane shutter.
Canon FD series interchangeable lenses with full aperture metering and AE coupling. Canon FL series with stopped-down metering.
Standard lenses for the Canon AE are Canon FD 55mm f/1.2 S.S.C, Canon FD 50mm f/1.4 S.S.C, Canon FD 50mm f/1.8 S.C
The S.C. refers to the lens' single coating, which Canon called Spectra Coating. The lens mount is FD, which is the same for both the TX and the AE-1, so yes, they are interchangeable. Multi-coated lenses were labeled "S.S.C." for Super Spectra Coating.
The Canon AE-1 is about as classic as 35mm cameras get.
