When originally produced the Folding Minex was available in 3 " x 4 ", 4" x 5" and 6 " x 4 " sizes. Later (c. 1919) a 2 " x 3 " model was made, postcard and 10 x 15 cm sizes were added in the 1920s.

The Tropical model was introduced around 1920. The camera was normally sold with a film pack adapter rather than slides. Standard lenses are in sunken mounts either wood or leather covered, telephoto lenses are surface mounted. Cases made of crocodile were advertised from 1926.

A cloth sleeve in the focusing hood is connected by a cord to the mirror mechanism. As the mirror is released so the sleeve moves within the hood to block out light from the hood.
