OpticalLimits 7/10
On a Sony NEX with adapter - It produced impressive quality figures in our lab. The resolution is good+ to very good at f/2 and reaches very good to excellent results beyond till diffraction is limiting the quality from f/11 onwards. Lateral CAs are well controlled and not overly field relevant. The bokeh fringing (LoCAs) is typical for such a fast lens. Distortions are basically absent. The most obvious weakness of the lens is the amount of light fall-off at f2.
