The Ermanox, first introduced in 1924 under the name Ernox, is a camera for 4.5x6 cm plates, made by Ernemann in Dresden. The camera has a huge and unusually fast Ernostar 85 mm f/1.8 lens (examples are also seen with a 100 mm f/2 Ernostar). It has a focal-plane shutter, with speeds 1/20 - 1/1000 second, plus 'B' and 'T'. Whether or not it was introduced as ERNOX is still under debate, none of the Ernemann catalogues support this name.
The unusually large aperture made available light photography a real possibility. It was this feature that made the camera famous, especially in the hands of Dr. Erich Salomon (1886-1944), who used it to make candids.
The first version of the camera has a rigid metal body (covered with black leather); the second version is a strut-folding camera. Both of these have the folding Newton viewfinder as shown here. A ground-glass focusing screen can also be used (one of the examples of the camera seen at Westlicht was sold with a screen, though the listing does not show a picture of it). There is also an SLR model, the Ermanox Reflex, which has a focusing screen on the top, with a folding leather hood.
A strut-folding Ermanox made for 9x12 cm plates, and in tropical materials (uncovered mahogany with brass fittings and brown leather bellows) has been seen at Westlicht; the notes suggest this camera may be unique (i.e. presumably made to a special order). It has a 16.5 cm f/1.8 Ernostar. Other non-tropical 9x12 cm examples with a 16.5 cm Ernostar exist and are in private collections.
