Overview

The Soligor 100 mm f/2.8 Auto is a vintage manual-focus prime lens known for its compact build and smooth handling. Optically, it delivers good sharpness in the center but shows softness and chromatic aberration at the edges, especially wide open. Build quality is solid with a metal barrel and smooth focus ring, though the aperture ring can be stiff. It suits photographers seeking a lightweight, affordable portrait lens for classic rendering, but edge performance may disappoint those needing corner-to-corner sharpness.
