Olympus OM-System Zuiko Auto-S 50 mm f/ 1.4 Review




Olympus OM-System Zuiko Auto-S 50 mm f / 1.4 is a fast lens for Olympus OM 35mm SLR cameras.

Produced from 1971 through 1984 and survived 6 modifications. Olympus OM-System Zuiko Auto-S 50 mm f/ 1.4

Practically all Zuiko lenses, which I used, sharp, and plastic. Have a nice character, have good contrast and are usually smaller in size than their counterparts from other manufacturers. For this Zuiko designers great thanks.

Another nice feature is that its price in the secondary market is now much cheaper Nikon same aperture. But in order to mount it on a Nikon require tricks, since the flange focal distance of Olympus OM less than the Nikon F.

At aperture f / 1.4 lens has a portrait sharpness, at f / 2 sharpness increases. And at f/ 2.8 is enough for most scenes. After f / 5,6 sharpness decreases due to diffraction.Olympus OM-System Zuiko Auto-S 50 mm f/ 1.4 test
