Summary: This lens is very sharp. The size is nice for holding. The weight is light. The price is reasonable. If that were not enough, the DXO on this lens is up there with the 24mm 1.4 which costs about $1500.00 more.
Summary: I just purchased this lens, ran a bunch of tests at high ISO at f1.8, 2.8 and 4, all available light at several distances - everything sharp as a razor. Used it on an assignment and very pleased with the images, clear, crisp and good color. When I opened the box, I was concerned because this lens is so light - the results are there, that is what counts. My work is primarily for publications, available light photography is the norm.
Overall a very good wideangle for landscapes, though not as flare resistant as Zeiss 28mm/2 ZF2 lens.

Summary: My favorite focal length for 35mm/Full frame has long been 28mm, and I have owned several 28mm lenses from Nikon and other manufacturers. The Nikkor 28mm/2.8 AFS-G lens is one of the best I have used, and once I got the best AF fine tune value set for my lens on my D800E (-15 for my equip, yours may vary), the lens has met most of my expectations. It is well suited to my landscape photography style.
