16-85 is a good choice... the build quality is very nice...
but you may not want to use the 85-end too much as the aperture goes up.... and the image there ... not very good
1750 2.8 ... never tried before, but many ppl say it's worth... and F2.8 is always attractive.
I'm planning to buy one macro lens for my d300. after looking around, I still can not decide...
Tamron SP90 2.8 Di VS Sigma 105 2.8 EX DG
Any suggestions for it? THX ;)
