Overview

The SMC Pentax-A 645 75mm f/2.8 is a compact, manual-focus normal lens for Pentax 645 medium format cameras, praised for its excellent build and handling—the focus ring is described as smooth and slick. Optically, it is very sharp with minimal distortion, aberrations, and flare, though corners are softer wide open. It produces pleasing bokeh and a '3D' look. A minor drawback is the 58mm filter thread. It suits landscape and general photography, especially on film bodies, and is a strong value.
