Shutter count problem.

After I reached IMG_9999 on my 40D, the shutter count went to IMG_0001. Something even stranger is that after about two hundred more shots, the shutter count went back to zero again. Has anyone ever encountered this problem and what would be the remedy?
Thanks

did you use multiple memory cards?

Yes, I've always used three cards and I usually format them periodically.

The rolling over of the numbers is the way it is designed. Look at the directory name, it got bumped up by 1.

If you are using multiple cards, you have to pay attention image # on the cards. The camera will automatically pick up the highest image # and set itself to that. It's not so much a problem with one body, but with multiple bodies it's pretty easy to do. There is a whole section in the manual that explains it in way more detail.

I'm pretty sure 9999 is as high as it will go. It's not your shutter count, it's just the file number. But it shouldn't reset after another 200 unless you accidentally changed the file numbering to auto reset, or you manually reset it. Just check in your camera's menu that it's set to continuous. You should format your memory card each time you're ready to use it again.

If you format, it has to be external to the camera. Formatting in camera will not stop the renumbering. That happens as soon as you plug in the memory card.

Do you mean you format the cards in a computer? I always used the camera itself to format them.

Sorry, I meant you should format for for the sake of doing what you can to prevent losing files.

magal, Canon intends that you format in the camera but there is a mindset here with many people that transfer images and format cards outside the camera. There are perhaps some valid reasons to transfer outside the camera using a card reader. Tripping over the connecting cord and pulling the camera off a table the major one, a dead battery during transfer being another and transfer speed being a consideration. In my opinion it is always better to do as the manufacturer intended as a first option.

I actually always use a card reader to transfer shots to the storage disc....its also much faster and does not cause any unnecessary drain on the camera's battery. As regards formatting of the card I've always done that in camera with no such problems before now.
