Bjørn's Rørslett's Overview:
Nikon designed this lens to yield sharp images even used for close-up photography. This was achieved thanks to its advanced 8-element design and a CRC feature acting on the front elements as with the 28/2 Nikkor. Images taken up close really are extremely sharp in the middle part of the picture and sharpness extends quite gracefully into the corners. Optimum near-focus sharpness is obtained at f/5.6 and f/8. For distant scenes, however, corner sharpness isn't that remarkable and ghosting under adverse conditions can be troublesome. There is some corner colour fringing present, too.
The close-focusing 28 copes very well with D2X, and for near subjects, you are assured of high quality images with virtually no CA issues (not yet tested for distant subjects with this camera).
The 28/2.8 behaved very well on the D3, and the vignetting into the corners is hardly an issue with this lens. It was virtually devoid of CA, too.
IR performance: A strong tendency to producing an ugly hot spot makes it a poor candidate for IR work. I've seen this issue with several camera models.
