I know i just made the 50D sound superior, it\'s just a little newer, and they were able to load the more recent technology, but the 40D is a phenomenal machine also !!!!
The Sigma 18-50 will definately work and do fine. The new Tamron 18-50 f/2.8 VC (vibration control) will act like the Canon \"Image Stabilization\" lenses the help supress camera shake at shutter speeds under 1/focal length. It\'s spec\'d to assist up to I think 3 stops, but even if reality is 2, your images are crisper, and it\'s engineered more recently along with the higher demand cameras with more megapixels(which I\'ve heard/read benefit with better glass). It\'s just a suggestion though, and your Sigma will definately produce great results on a 40D or 50D, just as it did on your 10D. Good luck
