I used to shoot a LOT with the old Nikkor 50mm f/1.4 S.C., and then the later 50mm f/2 Nikkor. One thing a 50mm user needs to learn is exactly howe to NAIL focus with the lens...focus is pretty important especially if you weish to use wider f/stops, like f/3.2 or thereabouts. THe thing about a 50mm lens is how versatile it is. It's a good lens in low light, but FOCUSING it exactly right is a big,big deal. The nice thing is that "most" 50's are usually pretty close to optimal at f/4.8 to f/5.6, which both give pretty fast shutter speeds during daylight hours, and when moving indoors and shifting ther camera to 1,000 to 1,250 ISO, a good 50 is a pretty handy lens!
