The Lumiflex is a 'pseudo-TLR' camera made by Lumière in about 1953; it is not a true TLR, as the viewing lens does not focus. It makes 6×6 cm images on 620 film. The taking lens is a Lumière Spector 80 mm f/4.5 with front-element focusing, mounted in a leaf shutter with speeds 1 to 1/300 second, plus 'B', and synchronised for flash. The viewing hood incorporates a small extinction meter which permits exposure estimation in combination with a calculator dial on the camera. The extinction scale in the meter shows the letters LUMIPOSE (the name of the meter) rather than numbers.
