The first model Square Reflector was released in February 1904, that model had the focusing hood held upright by two flat metal columns with a bridging piece at the top to which a binocular eye-piece could be attached. From 1909 a conventional focusing hood was used.

The SR was very expensive compared to other reflexes such as the Soho. It was available in sizes from 2 " x 3 " to half-plate. Different plate/film holders could be deployed. The front lens group was fitted with a bayonet mount, when removed it could be stored in a compartment in the side of the camera. The complete lens fitted into a shallow cup or cone which screwed into the front of the lens board, a quick-change bayonet fitting was available rather than the screw fitting. The lens cup could be replaced by mounts for faster or long-focus lenses. Normally a Protar was fitted but other lenses were supplied.
