The Canon EF-M was a manual-focus 35mm film, SLR camera which used the Canon EF lens mount. It was introduced in 1991 for export to the non-Japanese market, and was the only manual focus camera in the EF line. It was not sold as part of the EOS range; the camera's official name was Canon EF-M rather than Canon EOS EF-M.
The EF-M was in essence a Canon EOS 1000 without an autofocus system, a built-in flash, or a top-deck LCD. It was priced slightly cheaper than the EOS 1000, and relatively few copies were sold. It was not directly available in Japan, though some were re-imported.
Uniquely amongst Canon EOS bodies it had an optical manual focus aid, a split-image focusing screen as well as a ring of microprisms. This system was common with manual focus SLRs but had since fallen out of use in the autofocus era. The screen can be installed in several autofocus EOS cameras, and can only be obtained by purchasing a used EF-M.
