My XTI came today!!! (YEAH!) but one problem... my first shot is image number: 138-3807 Is this a used camera???? There is not a scratch or mark on it. I am using an old CF card in it but deleted all the pics from it prior to installing and reformatted the card in the new XTI prior to shooting. Perhaps this is the reason? Or does this particular camera start numbering where ever it pleases? EEK! Thanks for any and all help!
