I have tickets in Row B (second row from the stage) to see a show (LeAnn Rimes) at The House of Blues. Can anyone offer some tips on what lens(s) would be ideal from this distance. Would a 2.8 zoom suffice (and which one) or should I look at a prime. I am assuming I will have to crack up the ISO in either case. I am shooting in RAW, would I still try to expose to the right? Sorry for so many questions, but I have very little experience in this type of setting.
