Hey all, i've been pretty set on getting a 70-300 once my budget has digested the D7000, but a guest blog on Scott Kelby's site recommended the Sigma or Tamron 70-200 and forced me to reconsider.
I checked them out, and they can be found used for $600-$800. while the 70-300 goes for about $450.
I currently have a 55-200 so anything i get will be a considerable upgrade.
Anyone have any experience with these? its an intriguing possibility to get a 2.8 telephoto for this price. Are the 2.8's significantly better in IQ?
Any comparisons would be appreciated.
