Travis's suggestion is a good one. Your lens is very versatile but slowish. When the light is really low - a fast F1.8 lens is awesome!

You might also consider a macro lens if you really like close up work - this one - Tamron AF 90mm f/2.8 Di 1:1 Macro Lens for Nikon

gets good reviews and is about 500. new.


hope that helps
