The Magniflex is an uncommon Japanese 6x6 TLR camera. The viewing and taking lenses are both named Magni anastigmat, and are 80mm f/3.5. They focus by screwing out the front-element, with external gear-teeth to synchronise the focus of the two lenses. The shutter has speeds 1 - 1/200 second, plus 'B'.
Hiro Arai (author of the Japan Family Camera website) suggests that the camera is in fact the Crystar Flex, with the name removed wherever it occurred; notably the Magniflex has the lens name engraved on the front of the lens barrels, instead of a bezel. Arai states that the shutter is also labelled Magni (this cannot be seen in his pictures of the camera); but that having dismantled it, he is satisfied that it is an NKS shutter, like that of the Crystar Flex.
The Magniflex is not listed in Sugiyama.
