Nope. Canon dropped the ball on that one. As soon as you put it into Manual (you need to do this to fix both aperture and shutter, Auto ISO sets itself at 400.Having just got the 5 d 2 I'm loving it
And much better than 5d
The auto iso maybe useful
But was wondering if there was a way of doing this
Fixing shutter at say 500 appat at say f8 and then the auto iso could keep them fixed

This is fixed on newer cameras (the 7D at least does do auto ISO in M) but so far, this hasn't been ported back to the 5D2 firmware.
If it can increase the aperture to maintain shutter speed, before upping the iso (and 'potentially' degrading the image quality). When it runs out of aperture, it'll up the iso.
