Pentax smc Pentax 67 55mm f/4 - Pentax 67 Mount

This wide-angle lens for the Pentax 67 system provides a focal length equivalent to approximately 28mm in the 35mm format. It is highly regarded for its sharpness and minimal distortion, making it a staple for landscape and architectural medium format photography. The lens features a large 77mm front element and a built-in petal-shaped hood in the later versions. Prospective buyers should check for the smooth operation of the focus ring, as these large glass elements require significant torque. SDS examines the internal optics for 'Schneideritis' or coating degradation, as well as ensuring the aperture pins at the rear are straight and functional. Verify the condition of the rear mount, as the 67 system relies on a heavy-duty bayonet.
