I'm sorry if I came across harsh on the lens, I was still in a tiffle over the rant above it.
The 24-105 is a good lens, it's an L lens, it has fantastic quality, I just don't like it, but then again my first and still favorite L is my 135F2L, which is one of Canon's best lenses, period, so I have a personal high bar to compare against and I would pick my 135 over it anyday, and if I had to go wide I'd just put on my 17-40, which is also fantastic. So, I'm more personally biased against it, and I apologize if I came across calling it crap.
Dang, that was a long, run on sentence. Hope it made sense.
Oh, and bottom line... I"m jealous you can jump on a 5DII, my 20D serves me well but man I'm hungry for something newer.
