I know where you are coming from on this, Sean. I also have two good EF-S lenses (the 17-55mm f/2.8 and the 10-22mm wide angle), but I did make the decision to go with the 5D Mark II.


I don't regret this at all - it's a wonderful camera, but I found myself continuing to use my old 40D in conjunction with the EF-S lenses as well as the 5D. Now I finally have an option to get a really good APS-C camera that looks like it is going to have speed and auto-focusing capabilities almost as good as those previously only seen in the 1D series.


So between these two cameras, it's hard to see me having any real future need for a 1D camera and I can make full use of all my existing lenses. This is very good for my budget and my photography.
