Template:Japanese postwar 6×6 TLR (A–L) For the prewar and wartime Lyra Flex, see Lyra Flex.

The Lyraflex is a Japanese 6×6 TLR made in the 1950s. It is attributed to Katsuma Kōgaku by various sources. However the lens markings and shutter names seem to indicate that the company was still named Fuji Kōgaku at the time it made the Lyraflex.


The Lyraflex is an ordinary TLR. The taking and viewing lenses are geared together for focusing. Film advance is by knob and is controlled by a red window in the back, protected by a vertically sliding cover. The camera has a stepped nameplate written LyrafleX with a large "X" extended so that it underlines the rest of the word.


McKeown says that there are two versions, both having a Terionar 80/3.5 lens: the early one with a Fujikō F shutter (B, 1–200) and the later one with a Fujikō P shutter (B, 1–200, synchronized).[1]

Pictures of two examples have been observed, both with an ASA bayonet synch and a self-timer.[2] One of them is reported as having 1/200 top speed. No picture clearly shows the shutter name but the lens markings seem to be FUJIKOGAKU Terionar 1:3.5 f=80mm on the taking lens and LYRA Terionar 1:3.5 f=80mm on the viewing lens, only the taking lens having a serial number. The taking lens marking seems to indicate that the company had not yet changed its name to Katsuma Kōgaku and the viewing lens marking is similar to the marking observed on a postwar Lyra Six.
