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.
