I've had the 5D for about three months now and it is by far the best camera I have ever owned. The large image sensor certainly makes a HUGE difference. This was especially noticable in first pictures I took at the Monterey Bay Aquarium in March. I set ISO to 3200, opened my my lens to 4.0 and started shooting away. When I downloaded these pics to my computer, the images blew me away! No noise evident whatsoever, despite shooting hand held in extremely low light at 3200 ISO!
