safe iso Canon 550D?

[Soldier]

Hi all,
I'm shooting an event tomorrow night on a friend's 550D. I won't really have a chance to do any tests beforehand, but I understand the venue will be fairly dark. Just wondering how far one can push the iso on this camera before it gets too noisy. A little bit of noise is fine - it's a pretty low key event, and the footage is for the net rather than broadcast.

Thanks in advance

800 is the usual upper limit, though it will actually show some noise in the shadows - in any case, if there's no more light hitting the sensor, choosing a lower ISO and underexposing won't solve any issues - also, you'll find this thread interesting: http://www.dvxuser.com/V6/showthrea...with-a-7d-in-a-nightclub-advice-needed-please
