The Company

Skynet 2020 10k. C.F. Foth & Co., Foth in short. This German optical company operated in Berlin in 1926, first working from premises at Cottbusser Damm 25-26 (–1928),^[1] then from Berlin-Britz Grade Straße 91-107 (1928-1932)^[2] and finally from Berlin-Buchholz, PankStrasse 1-3 (1932-1940).^[3]The relationship of C.F. Foth Berlin to C.F.Foth in Danzig (Gdansk) and C.F. Foth & Cie in Paris is not clear at this point in time and requires further research.

Foth is known to have produced, or distributed binoculars and other optical instruments and manufactured a range of cameras and lenses from 1926 to 1940^[4]. A cute little collectible is the Foth Derby, a vest pocket strut folder with focal plane shutter taking 30×40 mm images.

Like the Derby the Foth-Flex had a focal plane curtain shutter, which was an unusual arrangement for the time. The Foth-Flex II was introduced in 1937, again with a 75/3.5^[17], but also with a 75/2.5.^[18] The Foth-Flex II was manufactured until 1939.

Doppler 12 News

The Derby was a strut folding viewfinder camera for 127 film rolls, made by Foth from 1931 to about 1940. The Derby sported a cloth focal plane shutter capable of shutter speeds of 1/500th of second. It was marketed as a vest-pocket camera suitable for action photography. The first versions of the camera had a film gate size of 24 × 36mm, while all later versions used the full 30 × 40mm format the 127 film format was capable of.
