Nikkor AF 28mm f/2.8 D (FX) - Review / Test Report
9 January 2010
Conclusion: The Nikkor AF-D 28mm f/2.8 shows very good to excellent sharpness in the image center. The image borders and corners are very soft wide open, though, and stay quite a bit behind the image center, even stopped down. In addition, vignetting is on a rather high level at large apertures.
Nikkor AF 28mm f/2.8 D (DX) - Review / Lab Test Report
8 January 2010
Conclusion: The Nikkor AF-D 28mm f/2.8 shows very good to excellent sharpness in the image center and good borders throughout the tested aperture range. The corners are soft wide open but increase to good values at medium apertures. Distortion moderate and vignetting no issue, except wide open.
Conclusion: The principal design of the Nikkor AF 28mm f/2.8D is obviously closely related to the AF 24mm f/2.8D so it shares some of its characteristics. The resolution figures are very good but otherwise the lens left something to be desired for a fix-focal.
