The Ermanox camera was launched in 1924 by Ernemann with a lens designed by L. Bertele. At the time of its introduction the camera possessed the widest aperture lens of any miniature camera made. The camera appeared in a number of different plate sizes, each with the f/1.8 lens and with the 4½ x 6cm. model being offered with f/1.8 and f/2 lenses. Reflex and collapsable models were also offered. It was listed until 1930.
