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.
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.
Adapted to Nikon F Mount Olympus OM-System Zuiko Auto-S 50 mm f / 1.4 is no exception and is made in the best traditions of the company Zuiko.
f / 2 aperture blades formed the shape of a circular saw f / 4 saw disappears and becomes an octagonal shape
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.

All photos were taken on Nikon D3100 camera. RAW export without postprocessing.
The lens has good sharpness.
f/ 1.4 sharpness at close focus test
Aperture f / 1.4 - 2 - 2.8 Crop 100%
At aperture f / 1.4 the 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.
f / 1.4 sharpness at infinity focus test
Aperture 1.4 - 2 - 2.8 - 4. Crop 100%
From experience, I can say that the use of the aperture it does not often cover more than f / 4.
Сharacter and bokeh
Lens have a nice character.
Bokeh so beautiful. I like more than the Olympus OM-System Zuiko Auto-S 50 mm f / 1.8.
Contrast and Color Render
My copy of the latest release of the series, and has multi-coating.
f/ 4 Contrast excellent. Backlit behaves well.
Distortion and vignetting
Distortion in the normal range. Yet there is, as at all high-aperture lenses. Also, holds vignetting in the normal range.
lympus OM-System Zuiko Auto-S 50 mm f / 1.4 is a great fast 50mm lens. Really like their character and bokeh.
f/ 1.4 Interesting for portraits and other art photography, which requires a small depth of field and beautiful bokeh.
