Both the Nikon 50mm F2.8 and the 28mm F2 lenses are very hard to beat. I have used both at some time or other in the past and can vouch for them. I did find that the manual focus versions are a tad better though. I wonder if it is the manufacturing tolerances required for these lenses to focus easily in AF mode could be to be partially to blame. Certainly the prices asked for by Nikon would suggest that more care is taken in their manufacture (notwithstanding more AF lenses are sold in this day and age)
