Hi all, Am thinking about the new 14-24 2.8. I already have a 17-35 2.8 and was wondering how they compare. I find the 17-35 a little soft in the corners at times and am wondering about the newer lens in this respect. Anyone have any first hand experience with each of these lenses? I am thinking of taking the 17-35 in for service (just a sticky focus ring), but at $85/h, am wondering if I might be better off investing that cash in the 14-24. Also, has anyone compared the 14-24 to the 14 2.8D ED prime? Thanks in advance!
