Is there any way to enable exposure compensation when using auto ISO on ANY Canon body. As far as I know it can't be done, but just thought I'd see if anyone knows something I don't. I like using exp comp in AV mode, but it would be better if I could expose to the right or left in M mode with auto ISO. Could this possibly be fixed with a firmware update in the future? I don't understand why the ISO selection by the camera couldn't simply be shifted, just as the aperture or shutter is in AV and TV, to over or underexpose as desired.
