okayy about my camera/lens's
so i have a nikon d70,
with a 18-85mm lens, the f-stop: 3.5-4.5 <--- yea i know its pretty slow.

anyways that lens just broke.... it wont autofocus if i use a fast shutter speed (like taking exposures of fast moving objects)

fortunately i recently got a 100mm tokina macro/portrait lens f:2.8 so its much faster!
its a really great lens for close up pictures.

also a very good friend of mine who is a professional photographer gave me a 50mm nikkor lens f.1.8 <--- one of the fastest lens's i have now!!!!!!!
its amazing.
(any nikon camera owners i suggest getting that lens. its so great for shooting in low light.... andd its small and compact. pretty great right?

ANYWAYY
any nikon fanatics have suggestions for one new lens to get?
im looking for a  wide variety/range so i could either get another lens like the one i had (18-85mm) or a faster one..... what do you people think?
