The Asahi Pentax Super-Takumar 105mm f/2.8 is a short telephoto prime lens in M42 screw mount, produced during the Super-Takumar era of the 1960s. It was designed as a compact portrait and short-telephoto optic for Pentax's Spotmatic-era SLR bodies, offering a moderately fast f/2.8 aperture in a manual-focus, preset-diaphragm-free automatic mount.

At UK auction in 2025, hammer prices for this lens have been modest, with two recorded sales at £50 and £90 — giving a median around £70. Because hammer results are wholesale saleroom levels (before commissions) and the sample is small, the value of any given copy today in 2026 depends heavily on glass condition and completeness; clean, haze-free examples tend to sell for the upper end of this range while tired copies drop toward £50.
