I have a new 5D that started to take images number 0001. After it hit 0125 it jumped to 7685. I think I may have switched cards, but now it keeps progressing from there. How can I tell how many images I have taken? Could this indicate that something is wrong with the camera? I use the zoom browser to load images and there really is no rhyme or reson for why the number jumped as far as I can tell. In fact, I was in the 8000 number set when I finished off with my rebel. Could it be that the camera is refurbished? I bought from Amazon as Amazon the merchant. I'm a little worried.
THanks!
