Canon 5DMKII fixed pattern noise at ISO 100
Jan 24, 2010

Hi,

I have been doing some random landscape work lately with 5D MKII, today I noticed some vertical bands in my photographs taken at ISO 100 (mainly in low contrast areas such as sky). Camera firmware is 1.2.4 lens used with EF 24-105 f/4 IS, I use canon DPP 3.7.2 for conversion of CR2 files, no exposure or shadow adjustment was done, all camera settings.

Here is the link to full size image, bands are subtle but if you have a color-calibrated monitor you should be able to see them in the right part of the photo.

I had this issue with a couple of night shots in the past, I contacted CPS and provided them with samples, their response was that they were not able to "see" the bands. Have you ever noticed this issue with your 5DMKII?

Regards,
AH
