The RE Auto-Topcor 58 mm f/ 1.4 is a fast normal prime lens for 35 mm Topcon SLR cameras.
Among experts this legendary 50 mm lens is considered to be one of the best. The lens is rather big. Just one fact to consider: it accepts 62 mm filters - a rare case for 50 mm lenses with the lens speed of 1.4.
It is sharp when wide open, but it produces ghosting in defocused zones. Bokeh considerably improves when stopped down to f/2.
