Korelle (3x4)

The Korelle 3×4 camera was a little strut-folding camera made by Kochmann, for 3×4cm exposures on 127 film. Nowadays it reminds us of modern compact cameras despite its heavyweight cute metal body which is covered with leather or leatherette. As a viewfinder the camera has two frames which unfold into view-through position by pressing the camera's unfolding button. A version with a little optical viewfinder and an accessory shoe was available. Year of release: 1931 (or 1930?) Manufacturer: Franz Kochmann Film Format: 3×4 cm Type: folder camera with simple two frame viewfinder Shutter: Compur shutter (by F. Deckel, Munich), exposure times 1 sec. down to 1/300 sec. Lens: Schneider-Kreuznach Radionar 1:3.5/5cm Aperture: 3.5 to 16 Dimensions: circa 12 x 7.5 x 4 cm (folded) Weight:	Korelle with Compur shutter and Radionar image by Uwe Kulick (Image rights)

Perhaps a cheaper version: Lens: 1:4.5/5cm Friedrich Coronar double-anastigmat (with unit focusing; necessary since front-element focusing is not possible with this lens) Shutter: Pronto everset shutter: 1/25 - 1/100 second plus B and T, with delayed action. Aperture: 4.5 to 18 (photo shows scale to f/3.5; scale was engraved both sides, and had been inverted)	imaging samples:
Kochmann also offered the camera with a Ludwig Lausa-Dresden Enoldar 1:2.9/5cm with aperture 2.9 to 23.
