I'm just processing some shots from last night, and for me this illustrates just how wonderfully good the 5DII is.
And why the 5DIII is struggling to do better!
Conditions were horrendous; very few cameras could have pulled this off.
5DII plus 70-200 f4 IS L and 1.4TC II
ISO 6400 (higher than I will normally go for a shot like this), f5.6 (wide as it will go), 280mm (fully zoomed) and hand held at 1/160s

(IS was earning it's keep).

Here's the 100% crop - I'm astonished how good this is considering EVERYTHING was against getting decent image quality. :shrug:
Noise reduction is just the LR4 defaults.

And the other thing that I'm amazed at is that the sensor has managed this despite red spotlighting!!
This is the unmodified original.
White balance was set to TUNGSTEN
