What it is
{"overview":"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. 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.","buying_guide":"Because this is a bellows-only lens, check that the aperture ring and blades operate cleanly with no oil migration, and inspect both elements for fungus, haze and cleaning marks under a strong light.

Questions
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.
