Switching from Nikon, my wife just bought an OM-1, and neither of us has been able to make much sense of the file system. I was going to go on with a complicated explanation of the problems here, but instead will just ask if anyone can help to interpret the options here.
I'm used to the Nikon system, in which once a number sequence is chosen, that sequence goes on whatever cards are present, regardless of what else is on the card. If a card fills up and overflows to the second slot, you can remove the full card, move the part-full one to the first slot, put an empty in the second slot, and it continues with no duplicated numbers. Any way of doing this on Olympus?
