I think probably you're about 1/2 to an f-stop off with this. Shooting at 125 is still something. I love to see this comparison with your 5DIf you had shot this at 1/60 it might have been spot on without editing. Of course, I don't know how far you've already pushed this with editing. However, I like the tonality
I know how tough it is to shoot in the auditorium and this is excelent. Again perhaps could be improved in post editing with removing some of the yellow and red cast. At 3200 this seems remarkable to me. I'd love to go in with the D80 and compare side by side.
Brad, the resolution is incredible here. Also you've got the white balance spot on. I t perhaps could have been brightened a bit but that's opinion of coursxe
