I have read the reviews on dpreview and a few other places. I want the 40D, because I want the Live view option (which i realize is limited). I really like the Panasonic's live view option with the swivel screen which is similar to what I have now and is great for the type of photography I am in to. From the reviews the Panasonic seems to take longer to auto focus and the photo quality may not be as good (the review was a pre-production model though) If I buy lenses for the 40D they should work if I ever upgrade to another canon, right? Like I said I am pretty ignorant on lenses. This is an overwhelming decision to make.
