Asahi Pentax Asahiflex IIB
The Asahiflex IIB is a 35mm single-lens reflex camera introduced by Asahi Optical in 1954. It uses a 37mm screw lens mount and waist-level reflex viewing, and sits among the earliest Japanese SLRs, predating the pentaprism-equipped Pentax line that followed later in the decade.
At UK auction, hammer prices for the Asahiflex IIB have ranged from around £81 to £190 across recent saleroom results, with a median close to £150. In 2026, clean working examples continue to sell for roughly £100–£150 at auction level, and the model's value is tightly linked to cosmetic condition, shutter function and the presence of a period Takumar lens. Earlier high-water results in the region of £180–£190 indicate what exceptional examples are worth when they appear.
