The rule of thumb for most security staff in ireland is, if a camera is the size of your hand and doesnt have a removable lens, its an amateur camera. Everything else is professional.
I asked a friend in Omaha who knows a couple of concert promoters to find out. He said security is to prohibit from entering and allowed to confiscate inside the arena (given back after the show) any camera that has a non-fixed lens and any camera with flash other then what you would find on a point and shoot.
Aww, Meatloaf is tame. Wade into the pit at a punk show sometime... a place I'd ONLY take a professional--or at least hockey puck--camera; cute little plastic things die too easy.
It's not that, I just have too much respect for my cameras to subject them to Meatloaf. I figure most Meatloaf fans are about 45 my now anyway. (I am 40, so I lived through the Meatloaf era myself.)
Now, I have had some punk experiences, but never with a camera. I was in London about 20 years ago and saw the Ramones at the Hammershmith Palais. I seriously thought that I was going to die once the band came on. I have never been in a crowd like that. Yikes!
