I'm in the hospital now for a regular surgery (don't ask!) and a fellow wedding photographer friend o mine came by with two lenses I wanted to play with. She was supposed to bring a third, but her workmate who owns it didn't come to work, so it was left alone.
Anyway... I'm in this dark hospital room (sharing rooms with three other women) and it's dark outside, only lights in this room are the reading lamps. And I was playing with these two lenses to see what I could get away with, as I am shooting mainly weddings, I need something that can handle well during tough circumstances.
Well, the 70-200/2.8L IS was of course no surprise. Excellent lens and it did what it should do in the circumstances we had, as I wasn't shooting stuff that was directly *in the light* but more shadowy areas. The focus was just a tad slow finding its target, but it was SPOT ON. And I got sharp images at 1/25 second. No surprise there, just encouraged me to want this lens even more.
So what about the 24-105? OMG! It totally surprised me! Wide open, tac sharp. It had no problems focusing at all (and fast!). I was handholding at 1/5 up to 1/25 second and had sharp images (ok, not moving objects, but this is a room that's about three times darker than the darkest church I'll shoot in, so it means I will get away with faster shutter speeds, or lower ISO (as I was shooting in 1600).
I'm definately going to choose between the 24-105 and the 17-55 now. Between wide angle or a bit longer. That's the issue right now that I have to fight with.
I won't post any examples here, but pixel peeping was done and I was raving!
Thanks to Noiseware I could clean up my 1600 ISO iamges and it's just gorgeous. WOW!
I'm sooooo in love! (I hope hubby is not jealous)

...Ann and I now shoot with these 2 lenses nearly all the time (Ann with 17-55/30D and me with 24-105/20D) and it would be tough to choose between them if we could only have one.
