As part of my Chrismas preparations I volunteer to shoot this show.
Starting off here with a few samples from the rehearsals.
D500 and Sigma 50-150/2.8OS pushed into service. The camera is VERY impressive under these conditions. AF puts the D3S to shame and high ISO is almost on par (when down sampled).
ISOs are from top to bottom: 4000, 5000, 12800, 6400.
