The CSR is an electronic-shutter SLR from Cosina introduced in about 1976. It accepts lenses with the standard M42 thread mount. Its most notable (and heroically misguided) feature is an optional accessory box which attaches to the top and provides autoexposure via motorized rotation of the shutter speed dial.
The same camera was sold in other markets under Vivitar branding, as the XC-2.
