Doing a bit of google-fu it seems that it is dependent upon exposure mode. In Manual, which is what I'm usually shooting when I bracket, it seems to go with shutter speed, but if I set my green button to set exposure in Tv rather than Av, it may bracket aperture instead. I'll have to try it. > Paul > >> I'm completely boggled why you can't choose what to bracket (shutter speed, >> aperture or ISO) since they're all controlled by the camera.
