The Asahi Pentax 28mm f/3.5 Super-Takumar is a wide-angle prime lens for the M42 screw mount, produced during the Super-Takumar era of the 1960s and 1970s. It was designed as a moderate wide-angle option for Pentax Spotmatic-era SLR users, suited to landscape, street and general reportage work.

At UK auction in recent sales, hammer prices for this lens have ranged from £38 to £70, with a median around £70 based on the limited records available. As of today in 2026 the 28mm f/3.5 Super-Takumar sits in the accessible end of the M42 Takumar market at saleroom level, and clean, haze-free copies tend to sell for the upper figures while scruffier examples see values drop sharply.
