The solely lack of perfection is that the far corners can generally be not quite as sharp broad-open, but it almost appears like extra of a sensor ray-angle interface drawback rather than the lens. While the dedicated ring is superior, with clicks engaged the barrel’s index mark and the ring’s tick marks do not all the time match up perfectly; Sony ought to both skip the third-cease tick marks or enhance the precision. The ring is metal, however the clicks really feel plasticy and less precise than we get from LEICA or Nikon handbook-focus lenses.
