Gebrüder Wenk (Wenk Brothers) was a camera maker in Nuremberg for a few years after the Second World War. The company also made spectacles, safety goggles and sunglasses.[1]

The company made three (or perhaps four - see below) models of the Wenka, a coupled-rangefinder camera for up to forty-five 24x30-mm exposures on a roll of 35mm film. The camera has a metal-bladed shutter behind the lens, with speeds 1/25-1/800 second (1/500 in model II), plus 'B', which is synchronised for flash.[2] Wenk filed patents describing the designs of the shutter,[3] the combined view- and rangefinder,[4] and even the unusual picture format itself (the patent notes that, when printed on paper sizes 9x12, 13x18, 18x24 or 24x30 cm, a picture in the well-known 24x36mm format 'must' be cropped, and states that only the postcard format favours the long frame).[5] There is a cold shoe near the left end of the top plate, and a synchronisation socket on the front of the body (to the right of the lens). The standard lens is a 50mm f/2.8 Xenar, stopping down to f/16 and focusing to 0.7m, with a 40mm threaded mount. A 100mm f/4.5 Westar was also made with this mount for the camera, but is rare.[2]

All models have a slim winding lever placed for the right thumb. The shutter release button is very close by the hub of this (surely inconveniently so). Beside this is a knurled wheel which sets the shutter speed.

  • Model 0a:[6][7] The first model of the Wenka is distinguishable by having two large rectangular RF windows. It also has the frame size '24x30' engraved on the top plate.
  • Model 0b: Scarcely a different camera; McKeown notes that on this model, the RF windows have bezels (absent before), and the cold shoe is screwed on (previously riveted). The camera is not engraved with '24x30'.
  • Model I: The left RF window is small and round on this model (and the model II, below); on the previous models there is a mask behind the left window to give the small RF 'spot'.[7]
  • Model II:[8] This model has a press-button by the lens to select X-synchronisation, and the top shutter speed is only 1/500 second.
