This was a handheld shot f5.6 1/15s with a 24-105 f/4L. Is this something that is related to the sensor property or firmware? Thanks for the inputs.

It looks like plain old high ISO sensor noise to me.

gjl711 Wait.. you can't unkill your own kill.  57,734 posts Likes: 4067 Joined Aug 2006 Location: Deep in the heart of Texas More info | Jan 16, 2010 18:53 | #5 5DII = fixed pattern noise. Actually many Canon cameras exhibit pattern noise. There is a thread here discussing fixed pattern noise. I'll see if I can find it. Not sure why, but call me JJ.
