Overview

The Pentax SMC 6x7 45mm f/4 is a large, heavy, all-metal lens typical of the Pentax 67 system's workmanlike design. It balances well on the camera, with a smooth but not butter-smooth focus ring and a positive-click aperture ring that resists accidental changes. Optically, it delivers satisfactory results, though it is slower at f/4, providing greater depth of field. Its build is tank-like, suited for professionals needing a durable wide-angle option for medium format.
