Medium format telephoto prime lens for Pentax 67 cameras.
The SMC Pentax 67 135mm f/4 is a standard-to-mild telephoto lens for the Pentax 67 medium format SLR system (6×7cm format). On the 6×7cm frame the 135mm focal length gives a perspective equivalent to approximately 68mm on full-frame — a near-normal to mild telephoto view suitable for portrait and documentary work.
135mm focal length, f/4 maximum aperture, SMC (Super Multi Coated), Pentax 67 bayonet mount, 6×7cm medium format coverage.
The 135mm f/4 is one of the most useful Pentax 67 focal lengths for portrait and documentary photography, providing moderate telephoto compression without the bulk of longer telephoto lenses. The Pentax 67 system's large 6×7cm negative format delivers exceptional image quality. SMC coating provides good flare resistance.
Inspect for fungus, haze, and coating condition. Confirm Pentax 67 bayonet engagement. Check aperture blades for oil-free operation. Test focus helicoid smoothness.
