Years ago, I worked for Pro Football Weekly, so most of the football I've done was from the sidelines with a field pass. I haven't shot any games from the stands for many years, so I'm not familiar with the rules these days as to how big a lens you can bring in without being told its not permitted. I'm sure the rules vary to a degree at different stadiums, but in general I was wondering if someone can tell me...
how long (or large) of a lens is generally permitted without hassle?
Is there more tolerance at the gate when you have a black lens as opposed to a white one?
I ask these questions for the following events.... Pro Football, College Football, Pro Baseball and Hockey. thanks!
