Ok, I have had some focusing issues with my 40D. It may be me or it may be the camera, I'm not sure. I don't feel confident using the camera at just that right moment when it presents itself. I like the feel, function, and quality of the 40D. I have tried to work with it for several months now, but it still isn't working for me. It would cost me about $200 to send it in to be serviced, but for that money and the price I can get for it as is(w/accessories) I bought a newer 50d that is a couple years newer with half the shutter count and in pretty good condition( I think). I know it is sort of a lateral move, but I feel that starting anew will be better in the long run. What are your thoughts of the 50D for those that have or have owned one in the past. All your advice or thoughts are welcome and appreciated. Thanks!
