I am so much on the fence between the Canon 24-70/2.8L II and the Tamron 24-70/2.8 VC. Would love to hear why you chose one over the other and if you are still happy with your decision. I am very aware of the physical differences between the two and the various test reports out there, but I am more interested in "how they feel and taste", if you know what I mean ... Comments?
Did you check out the review thread about the Tamron that was done by Dustin?
I bought the Tamron after I used / compared it with the Canon 24-70 f/2.8 II. The last one was a tad better in the corners and a tad faster AF but not significant for me to justify an additional 1000 euro. If money is no option and you need the best of best, then you may go for the Canon. I am very satisfied with the Tamron (which is also better than the Canon 24-70 f/2.
. And, I like the stabilization while using it in low light situations
