I shoot in raw only as a rule but set card in slot 2 to receive JPEG just in case I decide to shoot some. I thought card 1 would only receive raw and card 2 JPEG, but when I shoot raw only it pops a raw image on both cards just as it would if slot 2 was set for back up. Slot 2 overflow works ok, slot 2 back up works ok but slot 2 JPEG ends up with raw files in there and info display shows raw for both memory cards. I want card in slot 2 to stay empty ready to receive JPEG if I were to shoot any. Confused
