<p>My experience with taking concert photos is that depending on the type of performance it is, it demands a certain type of camera system.<br>
I recently took a D800 with a 70-200 f2.8 to a mostly acoustic music concert in small intimate venue. Every time I took a picture, I feel like everyone around me is staring at me and cursing because of the sound of the loud shutter.<br>
At a rock concert probably doesn't matter but I wished I had a newer mirrorless system that has a full electronic shutter. </p>
