The Velo-Klapp is a strut-folding 9x12 plate camera with a focal-plane shutter, made by Ernemann. The name might refer to the high shutter speeds offered by the camera, or it's speed of use; or the camera's compactness when folded, making it suitable to be taken on bicycle trips. The focal plane shutter makes the Velo-Klapp slightly bulkier and heavier than the Velocam, however, which has only a three-speed front shutter. The Velo-Klapp's shutter gives speeds up to 1/2500 second.[1] It was available with any of several lenses: Ernemann's own f/6.8 Detectiv-Aplanat, or f/6.8 or f/5.5 Doppel-anastigmats, an f/6.8 Goerz Doppel-anastigmat Syntor, or an f/6 Rodenstock Imagonal.[1]
The camera was available with a plate-changing magazine, for twelve 9x12 plates or twenty-four sheets of film in sheaths, a roll-film back, or a film-pack adapter.[1]
