Hey guys,
I'm looking at a 28-70 2.8 lens for a 20D. The Sigma has a DG (digital) rating while the Tokina does not. They are about $100 different in price.
Two questions:
1. Is there generally a quality difference (dust entering, durablity, etc.) in these two products?
2. Does the DG (digital) rating make a difference?
Thanks.
