    Overview

    The RE Auto-Topcor 20mm f/4 is a rare wide-angle lens, with only 1800–2000 units produced (MFlenses). Optically, it delivers good contrast and pleasant color rendition, particularly in 'blue sky' shots, though flare may occur with hood/polariser use (MFlenses). Build quality is typical of the Topcon RE Super system, which was professional-grade but heavy. It suits enthusiasts of vintage glass who value rarity and character over ultimate sharpness, especially on mirrorless bodies (MFlenses).
