From Fred Miranda's review, it was most impressive to me to see how well the D800 image did when the shadows were pushed. The results he obtained with the Canon 5D MKIII were disappointing enough to me that I borrowed a friends for a view days and I found the same problem, considerable color noise and banding. With all you guys shooting D800's out there how many shots have been taken at say iso 800 to 1600 and noise levels reviewed. Mainly in the shadows. The only review I have found was here: at Camera Labs.

Their results were pretty harsh on the D800 from 800 on up. But based on what Fred was able to do at iso 100, these results surprised me. I would love to see what some others are getting with the D800 at iso 800 on up.
