I have a question. I just received my brand new 7D Mark II, and have a question about the file names of the images.

The very first photo I took had a filename of EN8A9559.CR2. I know that the first 4 characters are randomized so you can tell which camera they are coming from (compared to other models that just have a IMG_ prefix).

However, are the last 4 numbers random on a new camera as well? I would have expected the first photo taken to be labeled 0001.

Brand new from factory or brand new to you? Have you checked the shutter count using a utility like EOS Inspector (OS X) or Dire Studio's Shutter Count? Was the card you used formatted or did it have images still on it?

It is brand new from the factory (or Adorama at least).

I think you solved this one though. The card wasn't formatted from my other camera and the last image on the card was IMG_9558. Guess the 7D2 was smart enough to see that number and go on to the next.

I haven't checked the shutter count, but maybe I don't need to bother with the explanation above.

Thanks for the help.

You found the issue. The file number assigned will always be one plus the greater of the last number used by the camera and the highest number stored in the current folder on the card.

Rename the file in windows to 0001 (make sure no other numbered files exist on the card), reinsert file into body and the next pic you take will be 0002

I ended up formatting the card and then did a manual reset on the counter from one of the camera menus. The real shutter count will be a couple hundred off from the file name, but at least I know I didn't get a supposedly new camera with almost 10k photos on the shutter.

I also took the chance to change the prefix to 7D2_ which is a little bit nicer than the 4 random characters.

Using X7D2 may be better, since if you decide to use Adobe RGB instead of sRGB color space, the camera will replace the first character with an underscore automatically.
