As expected, a winner !!

Processing is high, that is objectively quite heavy and optical and haptic any weaknesses can be discerned.

the image quality can be completely satisfactory, a lens correction is as good as no longer necessary quasi in post, the picture is almost perfect.
Vignette is minimal at maximum aperture, with color fringing I previously had no problems.

from maximum aperture of this lens is really sharp crack.
the autofocus is reasonably fast, quiet and works precisely.

briefly to what you get for your money here is actually worth 7-star ...

crystal clear razor sharp buy recommendation from me.
