That does look incredibly good for 1000 ISO
So much for all the b*** ***t about Canon using outdated sensor technology.

I uploaded a fairly large image so that it could be examined closely (3000 pixels long end). If someone were to tell me that this image was ISO 100-200, I would believe them.
But even at high ISO (5000+) where there is some grain, it is so smooth and film like that it is in no displeasing to my eye, and I'm pretty paranoid about clean images. I actually have a friend in Toronto that also just got a 6D who said this: "I bought the 6D a few weeks ago and very happy with it! One thing I am really loving is the quality of grain(noise) in high iso shots (12800 and over) - really film like!"
