Just thought I would state that I have re-discovered my 24-70MM EF L and I am delighted!
I pulled it out of the depths of my bag and put it on my 30D about a month ago to shoot a portriat session and it has remained there ever since. I have done two Halloween parties, two E-Sessions and a vacation trip with it in the past 30 days. Today I am using it to do Fall leaf photos all afternoon.
I have relegated my 17-55MM EF-S IS to the dRebel XT to be shared with my 10-22MM EF-S. Since I don't have another wedding for several months I plan to keep things this way until that event.
As many folks have stated here...the 24-70MM EF L is a fine, fine lens I am happy to have found mine again
