The Leotax Special D III is a Japanese 35mm rangefinder camera produced by Showa Kogaku in the post-war era, following the Leica screw-mount tradition that several Tokyo workshops adopted in the late 1940s and 1950s. It was positioned as a domestic alternative to imported Leica bodies.

Auction data for this model is extremely thin: a single UK saleroom hammer result of £769 in 2021 is the only verified data point we have, so any sense of what one is worth today rests on that lone figure rather than an established range. Because this is a wholesale auction price excluding commission, retail asking levels for a comparable example would typically sit higher, and confirmed value for the Special D III in 2026 should be treated as provisional until further sales appear.
