Ok! I just ordered a 50D at the local camera store on wild impulse because they are having it on sale and I will probably get it before the end of this week but I have a few questions for you guys. I have read a few reviews on that camera and it says that the high ISO performance on that camera is worse than my 40D and reduced dynamic range in the shadow areas compared to the 40D. The guy at the camera store told me the same story and he also told me that it's not worth upgrading from a 40D to 50D but since I will use it as a back up body so it doesn't really matter. My question for you guys is how the 50D performs in at LOW ISO speeds? and is it better for landscapes than the 40D because of the higher resolution? EDIT: and how about the long shutter speed noise on that camera?
