I did some tests myself when Fred first posed the problem which may counter that theory (for the *ist D ). I loaded my *ist D up with near discharged Ni-MH cells, put in my micro-drive, switched on AF, popped up the flash and started machine gunning at ISO3200. Not one frame contained signs of banding. I agree that the cause is likely a power supply issue but I was very surprised just how immune my *ist D was to any kind of power supply modulation. Maybe the *ist DS is worse in this regard?
