Based on capturing and processing in DPP many RAWs with a beta 7D, here are my impressions on the camera's noise characteristics. Note that this is a result of my subjective "visual feel," and not based on objective scientific testing or numbers.

1. ISO 100 is very clean and can take aggressive sharpening before noise starts to be noticeable in the shadows.

2. ISO 200 - 400 are not as clean as those of the 5D2, 40D, 1D2 and 20D. Noise (albeit very fine grained) starts to be noticeable in the shadows with aggressive sharpening.

3. ISO 3200 - 6400 have fine grained noise, but none of the banding I see in the 5D2. Even ISO 12800 has no or very little banding, but the noise grains seem to be larger, and as such this ISO is perhaps only useable for smaller prints or for greatly resized web photos.

4. I'm under the impression that the 7D's noise charateristics are optimized for print rather than pixel-peeping at 100%. I welcome this approach, as we can easily filter out the noise when posting web-sized photos. I haven't printed 7D photos yet, but when I compare these to my previous photos which were printed large, the 7D's fine-grained noise should do well in printing.
Pozwoliłem sobie pogrubić to co imho najważniejsze: szum z Nikona (niewidoczny lub lekko w druku), taki old-schoolowy bez bandingu.
