May I seek for your help. I set manual mode in my 5D Mark II with A=2.8, S=1/500 and ISO=Auto for indoor sport. The photo becomes under exposure because the ISO always turns up with 400 instead of higher figure like 4,000. It works well if I set Tv mode with S=1/500, A becomes and ISO becomes Auto. Can CHing teach me how to solve this problem? Thx!

50d have the same situation. I think this is normal.

At the page 58 (Chi Ver) of 5D2 user manual,
it showing that when you are using M mode,
the Auto ISO setting will be fixed on 400.
