Camera including data display - has two optical paths with manual switch to transfer data from liq. crystal display to film record

摘要

The camera shutter arrangement has a lens system (12) with a cover element (22) with a prism of semi-transparent type which transfers the light from a first to a second optical path in response to the movement of a manually operated switch. The information display system includes a liquid crystal element, which is exposed in the first optical arrangement. In the second method the light is projected onto a film in a direction almost at right angles to the film. The system enables the camera to record photographic data relevant to the exposure before the exposure is actually made.
