Unless you shot this at near night time I don't understand why the camera was set to ISO 6400. One thing about the D700 it's the low light king in my experience. Beat the crap out of my wife's 5DMkII.
Eric, My goof on the post. ISO was 1000, shutter speed was 6400. Aperture was f5.6. I was testing this new to me lens. The room was dark and there was fresh snow outside.
