What reviewers say

Both reviews find strong sharpness, solid construction, fast autofocus and severe 16 mm shading. The Digital Picture finds excellent wide-open corners, but inconsistent autofocus on some camera bodies. Photozone finds softer f/2.8 corners at the zoom extremes on its 50 MP test, improving stopped down; it finds little resolution advantage over the cheaper f/4 IS on 21 MP.
