The Asahi Pentax Super-Takumar 135mm f/3.5 is a classic manual-focus telephoto lens from the golden age of M42 screw-mount photography. Takumar lenses are celebrated for their excellent optical quality and superb build, and this 135mm is a popular and affordable way to enjoy that heritage.

The 135mm focal length is a traditional choice for portraits and medium-range telephoto work. It compresses perspective attractively, isolates subjects from their backgrounds, and allows comfortable working distance for candid portraits, street photography, and details in architecture or nature.

The lens uses a straightforward four-element design that renders images with good sharpness, natural contrast, and the gentle, slightly vintage character that many photographers associate with Takumar optics. Out-of-focus areas are smooth and pleasant, especially at closer distances.

Build quality is typical of Asahi Pentax in the 1960s: a solid metal barrel, a beautifully damped focusing ring, and clearly engraved scales. The lens is compact for a 135mm, making it easy to carry alongside a standard lens on a Spotmatic or other M42 camera.

The Auto/Manual switch on the barrel lets you choose between automatic diaphragm operation on compatible cameras and manual stop-down operation. The manual setting is particularly useful when adapting the lens to modern cameras, as it allows full control of the aperture with a simple M42 adapter.

Adapting the Super-Takumar to mirrorless cameras such as Sony E, Fujifilm X, Nikon Z, Canon RF, and Micro Four Thirds is easy and inexpensive. On APS-C or Micro Four Thirds bodies, the field of view becomes even tighter, turning it into an excellent compact telephoto for portraits and nature. It can also be used on Pentax K-mount bodies with the official M42 adapter.

Today, Takumar lenses remain highly sought after by film shooters and digital photographers who appreciate their quality construction and characterful rendering. The 135mm f/3.5 is one of the most accessible entries into this legendary lineup.

For anyone building an M42 kit or looking for a well-made vintage telephoto to adapt to a modern camera, the Super-Takumar 135mm f/3.5 is a charming and capable lens with real classic character.
