I believe it may be a proprietary connector. Smaller than the standard micro connectors on phones like Sprint uses. Should be able to use a USB extension cable. Several listed on Amazon reasonably priced. Or remove the memory card OR hook up with HDMI connector
It looks like it is proprietary for LUMIX, although you can probably buy an extension USB for it...not sure if you can find 6" with the right camera connection on it. Good luck. Very good camera for the money.
