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.
Optical Character
Bokeh
Gorgeous, smooth, well-controlled bokeh from the 6-bladed diaphragm.
Color
Neutral colour rendition with a faintly warm lean.
Sharpness wide open
Far from sharp wide open at f/1.4, usable at f/2–f/2.8, center peaks f/4–f/11, corners need f/5.6–f/8.
Flare resistance
Moderate veiling flare when backlit, with modest 'not too big,' appealing ghosts.
Contrast
Contrast drops at f/1.4 from longitudinal chromatic aberration, building back as you stop down.

Web research
Buy this lens if you want a fast fifty with genuine personality: a soft, dreamy, low-contrast glow wide open that flatters faces like few modern optics will, and a crisp, dependable center the moment you stop down. It rewards a photographer who chooses the look with the aperture ring and savors one of the best-built normals of the 1960s — the damped focus, the tactile clicks. Do NOT buy it if you demand clinical, edge-to-edge sharpness wide open, high contrast in backlit scenes, or corner performance without stopping down; modern lenses will out-resolve it and leave you cold to exactly the qualities that make this one loved.
