Overview

The Soligor 21mm f/3.8 Wide-Auto, a Tokina-made T4-mount lens from 1977, offers excellent center sharpness and color rendering wide open, with low coma and chromatic aberration. However, corner sharpness is weaker, especially on high-resolution sensors, requiring stopping down to f/11 for evenness (Glass, Metal and Silicium). Build is solid with a smooth focus ring, though stiffness occurs in cold weather. Bokeh is slightly harsh, and flare resistance is moderate. It suits budget-conscious photographers seeking a vintage wide-angle for APS-C, adequate for prints up to 30x45 cm (Glass, Metal and Silicium).
