Seriously, that camera will be completely fine. Keep anything you're unsure about at the bottom of your bag (as was said by someone else before) and they won't even find it.

When we went to see Jovi in Hyde Park (2003), they said no food or drinks containers over 500ml in size - this is absolutely tiny! I just took a backpack with me and, after having loaded it with 3 litre bottles of water and enough food in plastic containers to feed a small army, put my heavy coat in last. Security stopped me,

"Can I look in your bag?"

"Sure mate, no probs......"

Open it up and just explain that I'm carrying peeps' coats in case it rains and, "On ya go!" He didn't even bother having a rummage.

Nothin' to worry about at all believe me!

To be honest, they're not so bothered about people getting them in anyway cos, if your close enough to be using one effectively, they figure the stewards at the barriers will see you and ask you to put it away.
