The Graceflex[1] is a Japanese 6×6 TLR made in 1952 by the company Kigawa Kōgaku.[2]

It is the successor of the Tubasaflex and is similar to the last Tubasaflex I and II versions, with the later strap lugs. The main change is the shape and colour of the front plate, now all black, with a depression to leave place for a soft shutter release. The synch connector, of the ASA bayonet type, is protruding from the front plate instead of being directly mounted on the shutter housing. Of course the name plate has changed too, it is now all metal and written GRACEFLEX.

It is advertised in 1952[3] with a Bessel 80/3.5 coated lens and a KKK synchronized shutter, in two variants: the Graceflex I with B, 10–200 speeds, and the Graceflex II with the same speeds and a self-timer.[4] On these models, the shutter release is mounted on the right hand plate, like on the late Tubasaflex I and II. The advertisements also mention that this camera is equipped with a big loupe, it indeed looks bigger than the one equipping the Tubasaflex.[5]

A variant of the Graceflex II has been observed with a different shutter release, located on the right hand side of the front plate, instead of the right hand plate.[6] Another variant has been observed with the same shutter release and a big focusing tab on the taking lens.[7]


  1. The name is written in uppercase in one word on the cameras. In the advertisements it is sometimes written グレース フレックス with a space between Grace and Flex.
  2. It is attributed to a company called Daitoh in this page at, but this is surely a mistake (see Daitoh).
