I'm using a 5D and am baffled by the way it automatically allocates file names. These come in two formats ... i.e. _MG_6636.JPG or IMG_6637.JPG ... and it switches between these two formats for no reason I have yet detected, even within a sequences of images. It is somewhat annoying because it means the files do not sort in numerical/chronological order. Anybody know why/how it happens?
