The Folding Reflex was a very neat and elegant design. It was simple to set up and fold down, as the advertisements claimed. Pressing a catch on the folding bed collapses the focusing screen and mirror and releases the front standard which can then be pushed into the back of the camera. To erect the camera the front standard is pulled forward until it catches, the focusing screen is then raised by a lever on the side of the body.

The camera came in two models, the original (later called the Standard) with an f4.5 lens and, in early 1925, a model of slightly different dimensions fitted with an f2.9 or f3.5 lens, called the Special. The original was introduced in May 1921. Various standard lenses were offered as well as telephotos.

Some (? late) versions of the Standard have a catch fitted to the rising front which engages at the normal position. The price with 3 slides in 1922 was £55.0.0, this was later reduced.

A small number of cameras were made, or at least assembled, post-war around 1950.

The focal-plane shutter was not very rugged and today they often no longer work. Another problem is the catch which holds the focusing screen in place, this was prone to distortion (it is made of aluminium) and no longer works well.
