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,[1] 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.[1]

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).[1] 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 anastigmat. The camera was also made with Ludwig Vidar[2] 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.
