Asahi Pentax 135mm f/2.5
The Asahi Pentax Super-Takumar 135mm f/2.5 is a fast medium telephoto prime in the M42 screw mount, produced during the Takumar era for Pentax SLRs. It was aimed at portrait and short-telephoto work, offering a brighter f/2.5 maximum aperture than the more common 135mm f/3.5 sibling.
UK auction evidence is thin: the only logged sale, in April 2025, fetched £44 at hammer — a wholesale saleroom result that excludes commission and is well below typical retail asking prices. On that single data point the lens is currently worth around £44 in the auction market in 2026, though clean, haze-free copies in original condition can sell for more when they appear. With so few results, the price a given example sells for varies widely with cosmetic and optical condition.

Frequently asked questions
What is a Super-Takumar 135mm f/2.5 worth today?
Based on the single UK auction record available, a Super-Takumar 135mm f/2.5 is worth around £44 at hammer, though that figure reflects one wholesale saleroom result rather than a retail price.
How much does a Super-Takumar 135mm f/2.5 sell for at auction?
The only logged UK auction sale is £44 in April 2025, so current evidence suggests prices in that region, with clean examples likely to achieve more when they surface.
Is the Super-Takumar 135mm f/2.5 the same as the 135mm f/3.5?
No — the f/2.5 is the faster, less common variant in the Takumar 135mm line, while the f/3.5 is the more frequently encountered version.
What mount does the Super-Takumar 135mm f/2.5 use?
It uses the M42 screw mount, consistent with other Super-Takumar lenses of the period, and can be adapted to most modern mirrorless bodies.
