Hacking Canon’s Digital Rebel to make it into an EOS 10D Apart from few small differences in the software and body, the Digital Rebel, Canon’s entry-level digital SLR, and the EOS 10D, their professional digital SLR, are basically the same camera. It’s just that the EOS 10D costs five hundred bucks more. So are hacking the firmware on their Digital Rebels so that they can get access to all of the special features that are disabled on the camera that aren’t on the EOS 10D. Which has got to annoy Canon.
