Nice. Mine is a bit overexposed it seems. I guess the "looney 11" rule makes sense. On my LCD, f/11 looked a bit dark, so i just opened it up.
The problem with the old autofocus, I think, is that infinity is somewhere just before the stop on the focus ring, so I need to go to the stop and back it off ever so slightly. This should really be the only variable, since the exposure settings are pretty much fixed for shooting the moon.
