The Essential HDDSLR Shooting setup

I have my first professional video shoot with the Canon 7D coming up in about three weeks time. Which is not to say I haven’t shot video professionally before but I’m still nervous about stepping out with the 7D.

Do I go guerilla style and just take the camera and some lenses? Do I go all out and take everything but the kitchen sink? The more I look at my growing collection of 7D add-ons the more I think I don’t really need them.

So the question is: What HDDSLR equipment wouldn’t you leave home without? Do you take it all or is there a core setup that lets you handle whatever the shoot throws at you?

Let me know what you do….
