The Metz manufactured cameras also has an M/X synchronisation selector on the opposite side on the lens panel, and the fastest shutter speed is 1/300 sec.

However, only a limited number of lenses were made for the Mecaflex: The camera came in a small box complete with a zippered case and a metal neck strap.
