The Nikon 50mm f1.8 AF-S lens is a small, inexpensive, incredibly sharp lens. It'll perform as well as almost any lens you can buy.

This is the DF version introduced with the DF camera. Its design mirrors lenses from the 1970s and 1980s.

If you use your lenses in manual focus the DF version is certainly worth considering. The chunky focus ring feels great in use, almost as good as the original manual focus lenses.
