Asked to photograph a stage show!!! Need advice

Hi all,

Iv been asked to shoot an upcoming adult talent show - and I have never shot anything like this before... My photography skills start and end with static objects!!

The enviroment will be (a probably dark) nightclub, I'll be taking my 5d2 and 2 of my fastest lenses - sigma 50 and 85mm 1.4s. I know my 5ds focusing is not to great, but I have upgraded the focusing screen to a prescion focusing screenn incase I need to go manual.

So....I guess I'm asking if anyone has any advice - would I be recommend to shoot manual, or shoot with AF or even AF servo??

So basically, never done it before, dont want to screw it up and looking for any and all advice!!

Cheers

anyone?

Spot metering, af servo, lowest iso you can get away with. If they're using white spots on the subject, then expose for the bright skin, so it doesn't get totally blown out. Your body and lenses will be fine.
