Ernemann’s Klapp cameras were strut folding plate cameras for plate sizes 6.5 x 9 cm, 9 x 12 cm, 8 x 10.5 cm, 10 x 15 cm and 4 x 5 “. Built from 1901 to 1924, all models feature a focal plane shutter, a folding newton finder, and a focusable lens.
My specimen is one of the later designs (~1922) for plates of 6.5 x 9 cm with an Ernemann Ernotar f:3.5 F=12 cm lens. The focal plane shutter is still working like a charm and provides speeds from 1/20 to 1/1000 sec. plus T and B.
As for most plate cameras of that time you have to slide the ground glas off the camera body before you can place the plate holder. With the working shutter I wanted to take photographs with the Ernemann, of course. Problem is, the Klapp features proprietary plate holders. But it looks like all those plate holders got lost over time because in all the time I’m collecting vintage cameras none of them crossed my way. On the other side I have lots of 6.5 x 9 cm plate holders and a Rada rollfilm back for 120 film. Therefore I built a wooden adapter which allowed me to use the Rada back with the Ernemann Klapp.
