Why collectors want it
A staple fast fifty in both the chrome-nose breech-lock S.S.C. and later New FD versions. It is sharp by f/2 with smooth bokeh and neutral color. Canon FD has a short flange so it adapts cleanly to mirrorless but not to most DSLRs without optics.
Mount and adapters for the FD 50mm f/1.4 S.S.C.
The Canon FD 50mm f/1.4 S.S.C. has a native Canon FD mount. Canon FD is a breech-lock bayonet with a 42.0mm register, introduced in 1971 and replaced by the electronic EF mount in 1987. Every mirrorless mount has a shorter register than 42mm, so a plain mechanical adapter puts the lens at its design distance and infinity focus is preserved. The adapter needs a control ring (usually marked Open and Lock) that engages the stop-down lever. Mount the lens in the Open position, turn the ring to Lock, and the aperture ring then stops the lens down normally. FD lenses cannot reach infinity on any DSLR without corrective optics because 42mm is shorter than every DSLR register.
