fast wide angle zoom
I'm looking for a decent WA zoom lens, doesn't metter what brand. I'm using a d3100 at the moment, looking to upgrade to a d7000 in about a year (maybe the d7100 if it's good). I already saw the 17-50 f2.8 from Tamron, is it sharp? good focusing?
What would you recommend for me? the price range is on about 350 euros max.
thanks a lot!!
