Asahi Pentax Takumar 135mm f2.5 Bayonet Lens (Pre-owned)

The Asahi Pentax Takumar 135mm f/2.5 Bayonet Lens is a notable lens produced by Asahi Optical Co., Ltd., known today as Pentax. It was manufactured primarily in the 1970s and early 1980s and is part of the Takumar lens lineup, renowned for its optical quality and reliability.

Here are some key features and characteristics of the Asahi Pentax Takumar 135mm f/2.5 Bayonet Lens:

1. Focal Length: The lens has a focal length of 135mm, making it a moderate telephoto lens. This focal length is ideal for capturing subjects at a distance, making it popular for portrait photography, sports, and wildlife photography.

2. Aperture: The maximum aperture of f/2.5 allows for excellent low-light performance and the ability to create a shallow depth of field, resulting in background blur that can isolate the subject from its surroundings. It also provides flexibility in controlling exposure and depth of field.

3. Bayonet Mount: The lens features a bayonet mount for attaching to the camera body. Bayonet mounts provide secure and quick attachment compared to screw mounts, which were common in earlier lens designs. This makes it easier to swap lenses quickly when shooting.

4. Optical Quality: Asahi Pentax Takumar lenses are known for their exceptional optical quality. The 135mm f/2.5 lens typically produces sharp images with good contrast and color rendition, delivering pleasing results for photographers.

5. Build Quality: The lens is constructed with metal components, making it durable and well-built. It can withstand the rigors of regular use and is designed to last for many years with proper care.

6. Manual Focus: Like many lenses of its time, the Asahi Pentax Takumar 135mm f/2.5 lens features manual focus. This requires the photographer to adjust the focus ring to achieve sharpness manually. While this may require more effort compared to autofocus lenses, it provides precise control over focusing, which can be advantageous in certain shooting situations.
