Description — Pentax 55-100mm f/4.5 SMC
The Pentax 67 55-100mm f/4.5 SMC Lens is a medium format zoom lens purpose-built for the Pentax 67 mount system. Its focal length range runs from 55mm to 100mm, covering wide-angle through standard perspectives and giving photographers meaningful compositional flexibility without the need to carry multiple prime lenses. The maximum aperture of f/4.5 remains consistent across the zoom range, keeping exposure predictable whether you are shooting at the wide or tele end.
Focusing is entirely manual, which fits naturally into the considered, tripod-based workflow common in medium format photography.

At 1350g, this is a hefty piece of glass — build quality and size are inherent to covering the Pentax 67 image circle.
