That indeed sounds logical but I wonder if anyone has actually tried it.

I have. It's useless, 12 mm is too much. You can't focus anymore with the10-22.
That's ok for lenses with manual control of the diaphragm, for EF, or rather, electrically controlled aperture lenses it is more problematic. Closing down the aperture with the preview button trick IMO is quite usless, because focusing wide open is already tricky as it is with the little light coming through at large magnifications. Of course, LiveView may be a solution in that case, but metering may be quite off.
Kind regards, Wim
