Overview

The Asanuma Auto-Wide 28mm f/2.8 is a vintage wide-angle lens known for its compact build and decent optical performance when stopped down. It exhibits moderate sharpness in the center but significant softness and distortion towards the edges, especially wide open. Chromatic aberration and flare can be issues in high-contrast scenes. The all-metal construction feels solid, but the manual focus ring may be stiff on some copies. This lens suits photographers seeking a budget-friendly, classic look for film or digital use, particularly those who prioritize character over clinical sharpness.
