The basic operation of the camera -
at least in terms of exposure - is very similar to the EOS-3 and
other film EOS Cameras by Canon. An overview of these
controls is found on the film camera page.
Digital cameras have become almost a
commodity and their introduction and spread has been chronicled in
real-time on the web. One of the best places to get information on
most digital cameras is the site DPREVIEWS.COM.
This site gets the latest cameras (often before they are released),
reviews them thoroughly, shows you all the controls and features, gives
you example images, and compares the camera to its closest
competitors. I highly recommend viewing it. Also, the camera
manufacturers routinely place product manuals online.
