f1.4-1.8 with digital, man you won't need flash to freeze motion until your in the dark!
The AF-S, 35mm f1.8 G lens, got to be THE best bang for the buck with the "DX" sized dslr's.
Most times I don't even bother with my kit lens or my tele, the near instant focus speed, natural field of view, just a great great all around "fast", prime lens that just get's it done.
