The Dremoscop was also produced for the Leica - Leicascop, Contax - Contaxcop and for cine cameras. The Leica and Contax versions had simplified shutter and aperture settings. In use the film speed is set to an index, two arrows are then aligned on the scales. The finder shows two figures, the tube is turned until one disappears. The shutter speed and aperture pairs can then be read. The price was 30/-.

The 348662 patent was in the name of J.M. Bing of New York, a note in the Photographic Journal of 1930 says that Bing has been awarded a gold medal by the Photographic Society of Vienna. He was a Fellow of the RPS.
