Am confused .. which one would u select
Tamron AF 70-200mm f2.8 or Canon 70-200 4.0L.
My doubt is whether the 'L' cannot be compared with the additional one stop of tamron.
Also 1 more question.. Whats the best place to buy a Lens in the US, especially with thanks giving around the corner. Do they actually come up with good rebates every year or i shouldn't be expecting too much!!!!
