I've only had this camera a few months and I cannot figure out why I can't take over 1000 photos. I rang Nikon today and they were pretty useless but they told me I should be able to take up to 9999 photos. Problem is, if I take 1001, 1002, 1003 etc photos then it starts to rewrite over photo 001, 002, 003 etc (and for some reason it doubles the file too, so when I look at them on the computer there are two copies of each shot). I technically can keep shooting but I will lose the first 1000 photos I started with. Why is this happening? My memory card is big enough to take over 2000 photos. The guy from Nikon told me to turn ON the setting File Number Sequence but I'm not in the mood right now to take 1000 photos to test out if this has fixed the problem.
