I am considering updating my Canon 30D to the 40D. Why? I think more pixels would be good for larger prints say A3. And a larger screen with live view which I think would prove useful. I would be very interested in what you guys think. If budget was not a problem I would love a full size s/s sensor and 20+mp. Maybe if I waited a couple of years this would be available for a similar cost. Once again I would be interested in your thoughts on this, and do you think there is a deliberate hold back on technology?
