Can I attach Canon 1.4x III and 2.0x III extenders to my Canon 70-200 f/2.8 IS II USM at the same time and still get AF at 560mm f/8, or is this crazy talk?
Also I do a lot of Live View focusing for my landscape work, and always have the focus mode in the contrast detect "Live" mode (not "Quick" or "Face" modes) and it often switches inexplicably to the "Face" mode on it's own. I don't know if they are the correct mode names as I don't have the camera in front of me. It's a real "phenomenon" though - phenomenally annoying as it means I can't move the focus rectangle to where it needs to be! Anyone else get that?
