Mamiya Mamiya-Sekor 135mm f/2.8 - M42-mount

The Mamiya-Sekor 135mm f/2.8 is a telephoto prime lens featuring the universal M42 screw mount. Constructed with an all-metal barrel and an integrated retractable lens hood, it is noted for its smooth bokeh and pleasing colour rendition. It is a capable choice for portraiture and general telephoto work on both vintage film bodies and adapted mirrorless systems. When purchasing a used example, inspect the internal elements for dust or haze, which can occur in lenses of this age. The focus ring should operate smoothly without gritty sensations, and the aperture blades must be free of oil to ensure prompt closure. SDS checks the manual/auto switch for correct functionality and verifies the integrity of the rear mount threads.
