We expected a lot and we got much less. We found out the Fujinon is optically a sensible lens with a universal focal range, fast and accurate autofocus and a very efficient image stabilization.
solid, weather-sealed casing,, very good image quality in frame centre,, sensible image quality on the edge of the frame in the 16-50 mm range,, imperceptible longitudinal chromatic aberration,, better correction of lateral chromatic aberration than in the case of direct rivals,, slight coma,,...
weak image quality on the edge of the frame at 80 mm,, distinct astigmatism at 80 mm,, huge distortion in RAW files,, distinct vignetting in RAW files,, performance against bright light could have been better.
