The Showa Kogaku Gemflex (II) is a subminiature twin-lens reflex camera from post-war Japan, produced in the late 1940s to early 1950s when Japanese makers were building compact novelty cameras for the export and domestic markets. It is a small-format TLR aimed at users who wanted the waist-level reflex experience in a pocketable body.

At UK auction the Gemflex (II) is a thinly-traded collector item: recorded hammer prices range from about £250 to £360, with a midpoint near £310. Because these are saleroom hammer results rather than dealer retail, buyers paying through a shop in 2026 should expect to pay more than the figures the camera sells for at auction, and condition, completeness of case, and working shutter materially affect what an example is worth today.
