The Leotax FV is a 35mm rangefinder camera made in Japan by Showa Kogaku, part of the Leotax line of Leica-style screw-mount bodies produced during the 1950s. It was positioned as a domestically built alternative to the imported Leica rangefinders that dominated the Japanese market at the time.

UK auction hammer prices for the Leotax FV are thinly documented, with recorded saleroom results ranging from around £240 to £600 and a midpoint near £420. As of today that spread reflects how much condition, completeness and the presence of an original lens drive what a Leotax FV is worth, so buyers should treat any single figure as indicative rather than a firm market price.
