The Asahi Pentax Super-Takumar 135mm f/3.5 is a short telephoto prime for the M42 screw mount, produced during Pentax's Super-Takumar era of the 1960s. It was aimed at portrait, candid and middle-distance work on 35mm SLRs, and remains a common donor lens for mirrorless adaptation today.

UK hammer prices for this lens are modest: the two recorded saleroom results sit at £12 and £62, giving a median around £37 at auction-hammer level (wholesale, pre-commission). With only a small sample of sales, the spread reflects condition rather than variant premium, and in 2026 clean, haze-free copies tend to sell for the upper end of that range while scruffy examples change hands for pocket money.
