D600 Concert Photos: Trans Siberian Orchestra

First time with the D600 in a large arena.  These were shot from the soundboard with the Sigma 150-500.  
At f/16, I see about 20 "oil spots" on a white background.  As you can see, real world photos with this cam are amazing!!!  I am too busy shooting shows to get my sensor cleaned right now.  Maybe in a few months.  Loving this D600!!!!
