Well, when considering the move to the 5D Mark II and selling the 17-55mm, I was considering the 24-105mm f/4 L IS, the 17-40mm f/4 L, or the 24-70mm f/2.8 L as a replacement. Because of the amount of money involved in upgrading cameras, I was probably going to have to start out with the 17-40mm.


I've really become accustomed to having wide apertures and image stabilization available, and it's difficult for me to let go of either one. On Saturday I'll be shooting a wedding, and I'll probably be glad to have both. Oh, and props to Bryan on the review of the Bogen 640B monopod. I got mine a few days ago and tried it out last night. It's a very solid piece of equipment, and doesn't seem to feel as heavy as it looks. And the Bogen 234 Swivel Tilt monopod head holds up my 50D, battery grip, and 70-200mm f2.8 L IS lens quite well. I plan on using the monopod a little bit during the reception when I can't use the flash.
