Ernemann's Klapp-Cameras were made from 1901 to 1924. The cameras were strut folding plate cameras with focal plane shutter, focusable lens and collapsible Newton finder. The camera model was available in different sizes, for plate sizes 6.5×9cm, 9×12cm, 4×5", 8×10.5cm and 10×15cm.
Miniature variants were the Miniatur-Klapp cameras for the 4.5×6cm plate format. In 1924 a rigid body variant of the Miniatur-Klapp was launched, the legendary Ermanox.
