Never thought that could be part of or affect the problem... In fact, the striping or banding happens even when the batteries are full. > I have seen the striping effect at ISO 1600 and 3200 with good batteries > in the camera.

That's what I too had thought, shooting several single pictures close enough to be taken while the camera is writing on the card (and, apparently, not in continuous mode). At least, it's the only thing I can think of that may have an interference of some sort. I do not own microdrives, and the problem do happen using cards of different size and brands. I've experienced the striping at ISO 800, too, although it is not that visible. > This thread talks about the interference problem: > http://forums.dpreview.com/forums/read.asp?forum=1036&message=11720512 > > This thread talks about the microdrive problem: > http://forums.dpreview.com/forums/read.asp?forum=1036&message=11380387 Thanks for the help, Larry.
