I'm after a new lens to replace my kit 18-55mm (d40x kit lens), I've borrowed a friends newer VR version of the kit lens but it just isn't sharp enough for me. Ideally I'd love something that would handle lower light better as well.
So far I've found this Sigma 17-50mm f2.8 EX DC OS, though it's just out of my price range and not sure if I could get something as good cheaper.
I'm open to new and older lens, just want something sharper + faster.
My budget is around $500 max.
