Asahi Pentax Takumar 100mm f/4 Bellows
The Asahi Pentax Takumar 100mm f/4 Bellows is a short telephoto lens designed without a focusing helicoid, intended for use on a bellows unit for close-up and macro photography on M42-screw-mount Pentax bodies. It dates from the classic Takumar era and was aimed at users needing high reproduction ratios where the bellows itself provides focus travel.
UK auction data for this lens is thin: the only logged hammer result is £69 from March 2022, a wholesale saleroom figure rather than a retail or dealer price. On that single data point the 100mm f/4 Bellows Takumar appears to be an inexpensive specialist optic in today's market, and as of 2026 buyers should expect what it sells for to track closely with general condition rather than commanding any clear variant premium.

Frequently asked questions
What is an Asahi Pentax Takumar 100mm f/4 Bellows worth at UK auction?
The single recorded UK hammer price is £69 from 2022, so its value at saleroom level appears to sit in the modest two-figure range, though one sale is too few to define a reliable market.
How much does a Takumar 100mm f/4 Bellows sell for compared with a standard Takumar?
It tends to sell for less than helicoid-focusing Takumars of similar focal length because it cannot be used on a camera body without a bellows unit, narrowing the buyer pool.
Why is the price of this lens lower than other 100mm Takumars?
The bellows-only design means no built-in focusing, so the price reflects its specialist macro role rather than general-purpose use.
