Sounds pretty good although it doesn\'t match the 24-70 II (as expected from the MTF charts) at least at f/4 (although it\'s very close wide open to wide open). I\'d really be curious how it does f/8 though or even f/5.6 too. It\'s hard to say much more without knowing that. This sort of lens, in particular, may be used stopped down a lot.
Better than the 24-105 IS (or 24-70 I if you don\'t need f/2.8) though.
If the Tamron didn\'t exist I guess it might make sense at the price it was launched at, although it really depends how well it compares to the 24-70 II stopped down. Considering the Tamron though it seems a bit pricey (although, again, it\'s hard to say without seeing how it does stopped down, maybe it does better for 24mm landscapes?). It only tested a tiny bit better across the range and lacks f/2.8
It appears to deserve to cost more than the 24-105 IS but the Tamron does make the price seem a little rough, depending (on whether it is a trade of for getting access to f/2.8 vs. better stopped down landscape performance or something).
Of course large scale contrast and AF and such remain to be seen.
