in my opinion if you are a professional with press passes and you're getting paid to take the pictures why are you so threatened by an amateur bringing in a nice telephoto lens? you already get great seats to get shots and have sick glass so whats the worry? and honesly my 70-200mm from the second section behind home plate doesn't get me close enough for a super stunning shot but i like to use it to get closer than a 18-55mm and all.
