EOS 1D Mark II huge banding

[Ferenc]

Hi everyone,

recently I noticed huge bandings on my 1D Mk II images. Local Canon specialists advised this was definitely a sensor malfunction so I replaced the complete CMOS module but nothing changed. Colored stripes/blotches are clearly visible across the frame, especially in shadows. I've also made tests on different shutter speeds to determine if there is interference with diying shutter, but no correlation at all. I also tried different lenses, batteries, ISO-s, exposure pairs, bright and low-light scenes but the issue persists. There was a thread  by "Ukieboy" user last year here with the same problem like mine but the outcome of his case unknown. I'm attaching crops demonstrating the issue. Thank you in advance!

Best Regards,

Frank

Thank you for your answer! I created a new thread, but so far no one except you has responded, and regarding the camera, I also thought about the matrix, but the guy from the post changed it, the situation has not changed, I wouldn’t want to waste money again

Thank you for your tips. I tried tethered mode to exclude card writing part but stripes are still there. Also imported files to different RAW converters, no changes. By the way, the banding is visible even in the camera JPG-s.  Different shutter speeds and ISOs have also no influence. I have no more ideas.

But the question you seem to keep avoiding is whether the artifacts can be seen in the display of the RAW file before the conversion to JPEG. Unless the answer to that question is yes, the artifacts almost have to be a consequence of the JPEG conversion, no matter what RAW converter was used - even if it's the one in the camera. The elephant in the room is still what it was: you tried changing out the sensor (almost the only other plausible culprit), and that didn't help.

I guess interference wouldn't give you straight lines.
