Summary: I've got my copy for D90 and compared with zoom lens 16-85mm at 24mm for indoor portrait. It's very disappointing. The 16-85mm is visibly superior at 24mm than this 24mm prime including sharpness, chromatic aberration, distortion.
Summary: The optical design on this lens is outdated ! High vignetting at f/2.8 and clearly visible cromatic abberation when used on a D-SLR. The lens performs as a modern mediocre zoom lens.Not what you would expect from a Nikon prime.Resolution is decent.
