From the Liverpool and Manchester Photographic Journal (1977)

This is a 35mm SLR camera, using an aluminium die cast body, weighing 475g. Through-the-lens metering is by a stop down, match needle system with a sensitivity range EV3-18 at ASA100. The focal plane blind shutter is speeded B, 1-1/1000 sec. The camera also features a special detachable hot shoe fitting at the rear of the pentaprism. Two standard lenses are available, in the international screw-thread fitting: 50mm f/1.7 and 45mm f/2.8.

From the editor

The last camera made by Petri Camera Co., Ltd. The advantage of this model was its compactness, but it lagged behind its competitors in terms of functionality, since it did not have aperture-priority auto exposure mode / open-aperture exposure metering. No matter how cheap this camera was, it did not sell well.
