The Zuiho Opticalco. Honor is a Japanese 35mm rangefinder camera from the post-war era, produced as a Leica-style screw-mount body during the period when several small Japanese makers built cameras of this pattern. It was positioned as a compact viewfinder-rangefinder for everyday photography on standard 35mm film.

Sales data for the Honor is very thin: a single UK auction hammer result of £688 from November 2023 is the only reference point available, so any sense of what one is worth today rests on that one figure rather than a true range or median. Because these prices are wholesale saleroom levels rather than retail asking figures, dealer-listed examples in 2026 typically sell for noticeably more, and condition, completeness and matching numbers will swing the value significantly on a camera this scarce.
