You will do fantastic work with this new tool of yours Pascale. I have the Nikon D70 and I am very happy with it, but it does not make me want a 20D any less. Tom I think you need to take your camera back to the place where you purchased it, it sounds like you have a defective model or part. Everyone that I know that has the 20D raves about it. If your cam is under a year old it should be covered under warranty and this does sound like a warranty problem. Brenda :)
