Picked up my D3 yesterday and immediately fell into high ISO test mode. Incidentally, I think the reason we go there as new equipment owners is to test the limits of our gear and find it's operational boundaries. I don't know if I'll ever need ISO 6400 for a real shoot, but it is good to know it is there if you need it.
That said, I looked around our office for the darkest hole possible to test out my 50 f1.4 and the D3 at 6400. By the way, Program metering doesn't like the dark. It will make an exposure if you force it with the shutter button, but "Lo" is flashing in the viewfinder. I quickly changed over to manual and found the correct exposure after a few shots by 'metering' via the jumbo display. The shot below was literally shot in the dark. No lights were on in the room and the door was closed to the main IT room where this photo was taken. Inside the IT room is a small closet with equipment racks. The subject stood in the doorway of the closet facing the equipment rack. Notice the blue light in the background...that's a blue LED from a Dell Server about knee high to the subject. It puts out such little light, I didn't even see the blue on the background with my naked eye. I was surprised to see it render at all.
The crazy thing is that the subject's key light in this image is his iPhone! It's not even set to full brightness (about 75%). The warmer light is actually the monitor from a computer about fifteen feet away in the other room.
The image is a tad soft because it was hand held at 1/20th wide open @ f1.4.
Simply incredible!
