I'm debating whether or not to keep my 10-22. I recently took the plunge and purchased a 5D Mark II. In anticipation of its arrival I also purchased at 17-40. I opted not to get the 16-35 because I never really used the 10-22 indoors where I needed a wide aperture. If you were in my situation would you keep the 10-22 to use on the 50D or would you just shoot wide with the 5DII and 17-40? Thanks for your input.
