As I have no f2.8 zoom I would like to rebuy one for a wedding (also seen that I have the 50 1.4 Art, the 35 Art is close)
In past I allready had all 3 :
-Canon 28-70 2.8L (great old zoom, oop, sharp wide open, only 28mm)
-Tamron 24-70 2.8 (awkward zoom, but almost as sharp as the 24-70 2.8LII) some say bokey more busy, but didn't notice this.
-Canon 24-70 2.8 (not sharp @ f2.8)
I guess the 28mm vs 24mm will be a big difference again as it's on the wide part.

Which one would you chose and why ?
