    It does??? The loading must progress at a really rapid pace ... taking FAR less time than the rewinding at the end of the film.

    The theory behind this was to "save" film if the back was accidentally opened?
    When I first obtained this camera, I opened the back, not knowing that there was film loaded. ALL the film between spools was lightstruck ... not different than it would be with any other camera.

    Are you SURE about this?

    The idea is that there's a decreasing amount of film on the take-up spool and an increasing amount back in the canister as you progress through the film. So, if you open the back after 30 shots of a 36exp have been taken - most of the film is protected. I guess it protects the film you've taken rather than the film you haven't.

    Apparently only some of the EOS cameras do this, the Rebel series. Don't forget these are 35mm cameras, so by winding to the end and then going backwards if you open the back mid-roll you would only lose one shot ot two shors, the rest are in the cartridge. Of course the remaining film would be ruined, certain is better then losing all the shots you have taken.
