Basically, a motorized 500C/M. Same as the 500EL except the 500ELM has user changeable focusing
screens. Also, addition of TTL/OTF dedicated flash metering system (SCA 300 and SCA 500) compatible, and a larger mirror for increased brightness.
Camera only needs one battery to operate but will hold two, discharging simultaneously.
Built-in motor advances the film (up to 1.2 fps) and recocks the shutter after each exposure.
Operating Selector dial allows user to choose various pre-release options for mirror movement and shutter operation.
No shutter built in; uses C- and CF- lenses with built-in leaf shutters providing flash synchronization at all speeds.
