Sony's FE 16-35mm f/2.8 GM lens is a very good performer for a zoom lens and has plenty of features that will make it attractive to photographers. But it has some important limitations: such a wide-angle lens is not usually suitable for close-up work, although the 35mm focal length is usable with larger subjects.

Review
16mm Centre sharpness very good from f/2.8 to f/16, with f/22 being adversely affected by diffraction. The edges are almost as sharp as the center, with f/4-f/16 producing the sharpest results.
35mm Center sharpness is high through from f/4 to f/16, with f/22 being adversely affected by diffraction. The edges are almost as sharp as the center, with f/4-f/16 producing the sharpest results.
