Well I see that you are looking at the 15-85 as well....maybe the 24-105 is good for you as well. It isn't f2.8, but you get very nice IS and a longer focal range. And L build and quality.


For the extra money you would pay for an 24-70, you can buy a 50mm 1.4 or something to cover your real low light setups. Just a thought..
