100% crop
Please help. If I have to replace/repair my camera, that would suck. That would leave me with only ONE good body out of 3!!! The CF card has been used a zillion times with no problems. -Lloyd

Hard to say, maybe a ballast was going out in one of the lights near you at the time - scratch that if it is on more pics taken elsewhere - more info please?

I would try another card. Are you using some sort of UV or polarizing filter? Maybe try another lens? Short of those variables, I suspect it could be something wrong with the sensor. . I have Hoya UV filters on all my lenses. I've been shooting with them for years and never have seen this before. jra wrote in post #4391340 RF interference of some sort? Is this the only pic you've noticed this on? No, there are many others that I've found so far. I've shot in this location earlier in the year and had no issues either. Maybe there are a couple 'hot spots' that contain a huge amount of RF interference that I may have stepped into.

I'm hoping it's in one location. Then I guess it could be RF. ajpn wrote in post #4391358 One thing . . . under the similar threads there seems to be a lot of similar examples . . . Yeah I looked at a bunch, but none solidly hammered down a cause. And lots of them were about high iso noise banding. -Lloyd

Pulsing RFI. In the crop I see four pulses of (looks like) four cycles each. If we knew the shutter speed we could calculate the pulse rate and (approximately) the frequency of the RF. So when are the "anti-RFI" filters coming out? -Canon EOS 40-D with vertical/battery grip, wireless remote shutter release

My suspicion too. Old style inductive ballasts wouldn't do that, but switching ones do all kinds of funny things... "Be seeing you."
