ISO 5000 photos from a local theater production of "The Wiz" – RBFresno used the Nikon D3 and Nikkor 85mm f/1.4D AF to shoot the images, and said:
So there's a dance number, the lighting is OK for stage lighting, but not great for action. So what to do? Just crank up the ISO to 5000, set the lens @ f/1.4, and sit with my D3 on my lap waiting for enough musical noise to veil the shutter noise.
