Pentax Takumar 135mm f/2.5 Lens (Pentax K Bayonet Mount) (USED)

The Pentax Takumar 135mm f/2.5 in Pentax K bayonet mount is a classic, high-performance telephoto prime lens designed for photographers who demand sharpness, rich color rendering, and smooth bokeh. Engineered with a bright f/2.5 maximum aperture, this lens excels in low-light environments and offers precise control over depth of field, making it an exceptional choice for portraiture, stage performance, event photography, and fine-art detail shots. Built during the golden era of solid metal optics, it brings time-tested tactile handling to analog film shooters and mirrorless digital photographers alike.

Optical Performance and Bright f/2.5 Aperture

At the core of the Takumar 135mm f/2.5 is a refined optical formula designed to produce high-contrast, razor-sharp imagery even when shooting wide open. The fast f/2.5 aperture allows for faster shutter speeds in dim lighting without sacrificing image clarity. Beyond its light-gathering capabilities, the telephoto focal length combined with the wide aperture delivers subject isolation with a creamy, soft background rendering (bokeh) that brings portraits and key details immediately to the foreground.

Durable Mechanical Design and Precision Control

Crafted with an all-metal barrel and high-precision mechanical helicoids, this lens delivers a silky-smooth, long-throw manual focusing experience that modern plastic lenses simply cannot replicate. The physical aperture ring offers distinct, satisfying click stops for exact exposure adjustments. Featuring native Pentax K bayonet mounting, it mounts directly to classic Pentax 35mm SLR bodies and adapts seamlessly to modern mirrorless camera systems via standard, widely available lens adapters.
