I use both a 2.8/24 and a 1.8/50 on the D200 and neither causes problems of focussing, so I see no reason to expect that a 2/28 would prove a problem.
The above lenses of mine are both manual focussing ones.
As with all these screens, and also with the 500C/M Hasselblad systems, I wish that the makers would provide a grid screen with a split-image focussing device to suit all apertures of lenses. Nikon provided such a screen, but only for slow lenses...
