Olympus Zuiko 50mm f1.8
Eos 6D - Full Frame
The Zuiko S 50mm f1.8 has excellent sharpness and a semi-smooth bokeh below F5.6.
It is very easy to focus, even without AF confirmation, which makes it a good choice for use on a D-SLR. Contrast is slightly high and colors are slightly cool. Chromatic aberrations are very low.
Bokeh fringing is well controlled.
