Im asking myself already 3 months the same question and that is: what kind of camera can I bring with me to the concert? I have a regular one, but I also have a professional Canon 500D. I know that the regular ones are allowed but what about the professional cameras?
I also have a big camera (Nikon D50) and I brought it to some Scorpions shows. Everything was ok. But once I had a problem at show in St. Pete last summer. Security could take my camera if I was trying to make photos. So I couldn't do it.
