Topcor RE Auto-Topcor 58mm f/1.4
Exakta / Topcon RE
Overview
The RE Auto-Topcor 58mm f/1.4 is a cult classic from Tokyo Kogaku, Japan's second-oldest specialized lens manufacturer. Topcon was at the leading edge of 35mm camera technology — the US Navy even chose Topcon over Nikon as their primary 35mm system after extensive testing. This fast standard prime represents peak Japanese optical engineering from the 1960s.
Verdict: A cult classic for good reason. The Topcor 58mm f/1.4 delivers refined, smooth rendering that modern clinical lenses can't replicate. If you want vintage character with real optical quality — and can handle the Exakta mount — this is a hidden gem.
