The Plascaflex is a TLR camera for 6×6 cm exposures on 120 film, made in 1952 by Potthoff & Co. (later Montanus Kamerafabrik) in Solingen, West Germany. The name probably refers to the bakelite-like polymer the camera body was made from. Potthoff was a plastic moulding company, and the Plascaflex was its first camera.[1] It was sold in Britain as the Amplion-Reflex by Amplion, a company which mainly made radios and gramophones. It was also sold as the Raluflex I (this may be a name variant specifically of the V 45 model; both the example pictured in McKeown and one on the Web have an f/4.5 lens)[1][2].

There were two models, offering different levels of specification:

  • The Plascaflex V 45 has an uncoated 75 mm f/4.5 Plascanar taking lens, and a three-speed Vario shutter, synchronised for flash with a PC socket. At least in the Raluflex I, the lens is labelled 'Steiner Plascanar', and the viewing lens is an f/3.2 'Plascanar Special'.
  • The Plascaflex PS 35 has a coated 75mm f/3.5 Plascanar Anastigmat taking lens made by Staeble, and a synchronised Prontor S shutter, with speeds 1 - 1/300 second plus 'B', with a self-timer. The viewing lens is an f/2.8 Plascanar.

The camera's most unusual characteristic is the focusing magnifier stored in the bottom of the camera. In this same space an extra roll of film can be stored.

There is also a Plascaflex Modell II, probably a later model. The lenses on this model are called Pluscanar; they are an f/3.5 taking lens and an f/2.8 viewing lens. The name Pluscanar was used on the metal-bodied cameras (the Delmonta and its name-variants) which replaced the Plascaflex in the mid-50s, but the Modell II has the same plastic body as the original Plascaflex models. It also has a Prontor SV shutter, with the same specification as the Prontor S above, but with switchable M- or X-synchronisation. The Atlantiflex Super appears to be similar to this model.[3]
