Olympus OM-1 Analogue camera

The OM-1 is an all-mechanical SLR. It has a very large viewfinder (allowing high eye relief if desired) with interchangeable screens but a fixed prism. It also has a through-the-lens exposure meter controlling a needle visible in the viewfinder. The camera does not have automatic exposure: the user has to use the aperture and speed rings to make a correct exposure. It has a very compact body, whose form was retained in later models. Unusually, the dial on top of the camera is only for film speed--shutter speed is set by a ring around the lens mount as on many leaf shutters. This would be standard for the single-digit OM series, as it allows the photographer's left hand to focus, adjust aperture and adjust shutter speed quickly without changing position.

This camera is used by a professional photographer who toke good care of his equipment. Little dust in the finder and little signs of use.

I did a small test with expired ilford HP5 film. See pictures, the test strip and a test scan. Strip looks a bit dark because of the use of expired film.
