I saw complaints about "noise" at low ISO, "artifacts" and "maze pattern" of the 5D2 from three 5D2 owners.
The phenomenon is something like
|IMAGE IS A REDIRECT OR MISSING!|
MIME changed to 'text/html' | Content warning: script
this is created by ACR from a raw image, sharpened, here in 3x magnification.
The source of this pattern is the faulty sensor; the demosaicing misinterprets the phenomenon and that causes the mase-like pattern.
Is this phenomenon known here, has anyone encountered it?
