I have the 50D and first thing i did with it was to take it out for a test at Hi1 and Hi2 and i got horizontal bands all through the image... I don't mind noise.. in fact i love grain in my black and white images, but this banding makes these ISO levels useless... what gives? Canon EOS 5D Mark III | Canon EOS 7D | Canon EOS 70D

Oct 23, 2008 23:10 | #8 and to boot, I can see the horizontal lines right on the LCD screen of the camera, so I don't think it has anything to do with post processing in ACR as I've seen posted somewhere else on these forums... its simply awful. Canon EOS 5D Mark III | Canon EOS 7D | Canon EOS 70D

Oct 23, 2008 23:11 | #9 1600 is great... 3200 is not so bad... but anything higher shows banding in the shadow areas... i have firmware 1.02 by the way. Canon EOS 5D Mark III | Canon EOS 7D | Canon EOS 70D

Oct 24, 2008 10:07 | #13 I noticed with my 50D that the banding is much worse when in the same room using those new compact flourescent light bulbs. I suspect the higher gain amps in the camera are somewhat sensitive to emitted RF energy. I've not tried any high ISO yet out in the country away from interference to confirm this theory. But, the fact that it varies depending on what room I'm shooting inside my house makes me think there is some validity to this. No, I don't have samples, deleted them all after playing around. However, the in camera JPEGs come out pretty good even at high ISO. Gear List

Oct 24, 2008 11:47 | #15 Here are two images... the first is the a reduced image of the 15mp file.. showing the banding.. Iso 12,800 shutter 1/160th and f/7.1
and a 100% crop
I've also just noticed all these little white specs in the 100% crop... that concerns me a bit.. its like they are missing bits of the photo... pure white... not too happy about this... Canon EOS 5D Mark III | Canon EOS 7D | Canon EOS 70D
