I've been doing a lot of research into a particular noise issue I seem to be having with the 5d mkII. I haven't yet found another photo exhibiting the same condition. Yes, I realize there are banding issues currently with the mkII, but the issue I'm having - I can't find similar examples. I seem to be getting not only banding, but a "linen-like" horizontal + vertical noise pattern in the shadows. Here are 100% crop examples with different lenses in different lighting conditions:
Here is the EXIF for this photo:
5D Mark II - Canon 50mm f/1.4
1/5s @ f/1.8
5D Mark II - Canon 24-105mm f/4L
1/60s @ f/4.0
(the arrows indicate noticeable banding)
Are these patterns normal, or should I be concerned? Thanks very much for your analysis!
