Overview

The Cosinon-W 28mm f/2.8 MC is a vintage wide-angle lens with a Pentax K mount, noted for its chic image quality but tendency to produce slightly dark photos, which is considered a feature rather than a flaw. Build and handling are straightforward, requiring no adapter on Pentax DSLRs. It suits enthusiasts of vintage lenses seeking a unique, slightly moody rendering, especially for film or digital use with appropriate adapters.
