The Asahi Pentax Auto-Takumar 55mm f/2.2 is a standard prime lens for early Asahi Pentax M42 screw-mount SLRs from the late 1950s. It was supplied as a kit lens on bodies such as the Pentax K and S2, offering a moderately fast normal field of view for general photography in the era before fully automatic diaphragm coupling became standard.

Sales data is very limited, with one UK auction hammer result of £56 recorded in March 2022 — a wholesale saleroom level rather than a retail asking price. On that basis the Auto-Takumar 55mm f/2.2 is worth a modest sum today in 2026, and clean copies typically sell for similar two-figure money when they appear, with the f/1.8 and f/2 Takumars usually carrying a price premium over this slower variant.
