The XR-1 requires two 1.5v silver-oxide batteries only to power its match-needle light meter, using CdS cells within the pentaprism housing. The vertically-traveling, metal focal-plane shutter is entirely mechanical. This offers speeds from 1 to 1/1000 sec. and a 1/125 flash sync speed. Unusually, there is a multiple-exposure function provided, using the "M.E" button on the rear of the camera, below the wind lever. There is a window above the lens aperture ring which allows the selected f/stop to be viewed through the viewfinder.
The 1979 XR-1s version is also able to accept a motor winder, and its ME button gains a lock against accidental use.
