It looks like a very good lens but I must admit I hoped it would be a bit sharper wide open. I\'ll wait for more reviews before making a final judgement. In any case, kudos for Tamron for being the first in this niche.
While the 24 1.4 II L handily beats it f/4 and lower, at landscape shooting like f/5.6, f/8, f/11 the Tamron actually scores sharper center, mid and edge with less CA!
That is pretty stunning performance. I\'m not sure the 24-70 II can beat that level for landscapes although it may tie. I suspect it will do noticeable better f/2.8-f/4 than the tamron though.
Tamron has IS and costs a lot less though.
At the very least this new Tamron will make the 24-105L look silly and should handily beat the 24-70L original (other than for AF speed) and tamron 28-75.
I\'d wait on a few more reviews though since lens testing is a notoriously finicky business.
