The Asahi Pentax 85mm f/1.9 SMC Takumar is a fast medium-telephoto prime in the M42 screw mount, made in the late manual-focus Takumar era and aimed at portrait and available-light shooters who wanted a brighter alternative to the more common 85mm f/1.8 and 105mm options. With its multi-coated SMC optics, it suits classic short-telephoto duties on M42 bodies and modern mirrorless cameras via adapter.

UK auction data for this lens is thin: a single hammer result in November 2025 sold for £110, which sets the only confirmed saleroom benchmark we have for 2026. Because these are auction-hammer prices — wholesale levels reached in the saleroom rather than dealer retail — clean, fungus-free copies typically sell for more once handled by specialist dealers, but the £110 figure is the most reliable indicator of what an average example is worth at auction today. With only one sale on file, the price a given copy sells for can swing widely depending on glass condition and whether the original caps and case are present.
