The Velo-Klapp is a strut-folding 9x12 plate camera with a focal-plane shutter, made by Ernemann. The name of the camera probably refers to it'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]


Notes

  1. 1.0 1.1 1.2 Catalogue Ernemann Cameras sind die Besten; Anleitung; Liste No. 91, p.14. The catalogue is undated, but describes the Bob III (1924-26) as new; at Ciné-Ressources. The Velo-Klapp and Velocam are shown on facing pages, and the Velocam is specifically described as for alpinists, cyclists and tourists.
