Give my 20D away? Yeh sure.... in your dreams <g>
I am actually achieving now what I have wanted to do for years but could never afford it: having two bodies in my camera bag so that I have back up. My 40D will become my main camera (of course!) and the 20D will come with me on pro shoots. I'll sometimes use it with a wide lens on it so I can quickly switch between wide and telephoto.... Red Arrows for example
