{"overview":"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. With so few results, the price a given example sells for varies widely with cosmetic and optical condition.","buying_guide":"Inspect the front and rear elements under a torch for fungus, haze and cleaning marks, since Takumars of this era are commonly found with internal haze that softens contrast. Check the aperture blades for oil and confirm they snap closed cleanly, and turn the focus ring through its full travel to feel for stiffness or grease migration.

Questions
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.
