Hi Troy,

These were taken using mini-usb to usb cable straight to laptop.
Banding is present using camera battery and DC-AC adaptor.

Banding is less obvious when taking an image through EOS utility.

My understanding is this banding is present through a wide range of Canon cameras; but how to get rid of it in the 'lights' ?
