Cincinnati freelancer Ryan Dlugosz has written up some concert photography tips. I'd question the use of primes over zooms but then compare Ryan's work to mine and I think he's the guy to listen to!

I just can't imagine shooting that Elton John concert, for example, with primes. If I'd used primes then I'd have probably gone for a 135mm on one body and a 14mm on the other, but on the day I don't think I used anything close to those two focal lengths. Changing lenses would have been practically impossible with the time restriction and so many other photogs bustling around in a small area.
