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

Key Features:

• Focal Length: 135mm, which is considered a medium telephoto lens. It's great for portraiture and nature photography, providing good compression and subject isolation.

• Aperture: f/2.5, which allows for relatively fast shutter speeds, even in lower light conditions, while also providing good background blur (bokeh) for portraits.

• Mount Type: Bayonet, specifically the Pentax K-mount, which allows for easy attachment to Pentax cameras. The Takumar lenses were traditionally used on Asahi Pentax and other Pentax SLR cameras, though it can also be adapted for use with other cameras using an appropriate mount adapter.

• Optical Design: As with many Takumar lenses, the optical quality is highly regarded, especially for sharpness and rendering of colors. They are also known for their rich, smooth bokeh.

• Build Quality: Takumar lenses, including the 135mm f/2.5, are often appreciated for their solid, metal construction and mechanical durability. They tend to be quite heavy and robust, providing a satisfying tactile experience.

• Manual Focus: The lens uses manual focus, offering precise control for photographers who enjoy the hands-on approach.

Performance:

• Sharpness: The Takumar 135mm f/2.5 is known for its sharpness, especially when stopped down a bit from its maximum aperture. At f/2.5, it provides decent sharpness, but for optimal results, photographers often stop it down to around f/4 to f/5.6.

• Bokeh: The lens produces a smooth and pleasant bokeh due to its aperture design, making it a favorite among portrait photographers.

• Color Rendition: Takumar lenses are celebrated for their warm, accurate color reproduction, contributing to an organic and pleasing aesthetic.

Compatibility:

• Pentax SLRs: It was originally designed for film Pentax SLRs with the M42 screw mount (or later the K-mount), but modern digital Pentax cameras, as well as mirrorless systems like Sony, can use adapters to mount these lenses. However, you might need to use the lens in manual mode since it lacks autofocus capabilities.
