someone knows where the serial number of the xl-1s is located ?

In he battery slot. Remove your battery and you will find it. The serial number of the lens is located on the black circullar plastic piece on the mount. Remove the lens and watch near he electrical connectors.

ah, got it, thanks !

Just wanted to leave note here about how valuable this little thread was as I scramble to document my camera gear with hurricane Frances heading my way. Thanks.

Where in FL?
