The Korelle 3×4 camera is a little strut-folding camera made in about 1931 by Kochmann of Dresden, for 3×4cm exposures on 127 film. It has a compact metal body (about 12 x 7.5 x 4 cm), with leatherette covering. The camera was first introduced as the Korette, but was renamed within the first year of manufacture. The name is usually impressed in one of the front panels of leatherette, but is sometimes absent; McKeown shows an example without the impressed Korelle name, and states that the camera was also sold by Herlango of Vienna, under it's own name.
The front of the camera is self-erecting on its struts upon pressing a button on the body. This also releases the folding viewfinder. In most examples seen, this is a simple pair of metal frames; however, McKeown shows an example which appears to have glass in at least the front frame (and so is a Newton finder).
McKeown gives a long list of lenses with which the camera was available, including f/3.5 Tessar, f/2.9 or f/3.5 Xenar, f/2.9 Cassar, f/3.5 or f/4.5 Radionar and f/4.5 Trioplan (all of these are 5 cm). He refers to a 'no-name' example with an f/4.5 Soetar-Anastigmat; another 'no-name' example is pictured below, with an f/4.5 Friedrich Coronar double-anastigmat. The camera was also made with Ludwig Vidar and Enoldar lenses. Most cameras have front-element focusing, but this is not possible with some of the lenses (such as the Coronar, which is a symmetrical lens), and these cameras have unit focusing, with a large focusing ring behind the shutter. The shutter may be a Vario, Pronto, Ibsor or a Compur.
