Yes , all where shot f2.8 using 70-200 vr2 on nikon D3. ISO vary from 1200 to 6400. I love this lens, my other lenses too ;)
2.8 was good enough for stage pictures, for fire dancers is more tricky and difficult .
I know your equipment RViiiper, 24-70 is nice lens .
I'm glad you like it
btw, Its still a hobby have not made a penny on my pictures yet:)
