I'm not a big fan of Nikon's 50/1.8 when it comes to sharpness. Over the years I've had 4 of them, ranging from the 50E, 50AF, 50AFn, and lately 50AFD.
In theory, its reason for being is the f1.8 aperture that should let you shoot at less than ideal light. But that's theory. From f1.8 to f4, they're so soft, that you get better results with some slower lenses and ISO bumped up a stop or two. The 50/1.8 needs to be set at f8 to get really sharp, and by then, what's the point of the 1.8 aperture?
If you're looking for better lenses in the same price bracket, the already mentioned 28-70/3.5-4.5 is lots and lots better (probably due to its molded aspherics). Another option would be a Sigma 50/2.8 1:1 macro if the 60/2.8 would be pushing your budget. The Sigma's auto-focus is geared slower than the Nikons, but again it's a lot sharper than the 50/1.8.
