Pentax 28mm f3.5 SMC Pentax-M Lens

The Pentax 28mm f/3.5 SMC Pentax-M is a manual focus wide-angle prime lens built for Pentax’s K-mount SLR system, produced as part of the compact M-series lens lineup. At 28mm with an f/3.5 maximum aperture, it delivers a moderate wide-angle field of view well suited to landscape, architecture, interior, street, and environmental photography. The SMC designation refers to Pentax’s Super-Multi-Coating applied to the optical elements, intended to reduce flare and ghosting and improve contrast and color transmission compared to uncoated or single-coated alternatives. The M-series designation indicates a compact and lightweight construction aimed at reducing the overall size of the lens relative to earlier Pentax wide-angle designs. Fully manual operation covers both focus and aperture adjustment directly on the lens. Compatible with Pentax K-mount film and digital SLR bodies, and adaptable to mirrorless and other camera systems via third-party Pentax K-mount adapters.
