Just bought a GH1 (body only) from Wall Street Photo (through Amazon). The camera is NEW. However, I noticed two things: 1) it's made in China (all my other Panasonic cameras are made in Japan); 2) the Video Out setting in the wrench menu defaults to PAL as opposed to NTSC. This made me think that perhaps this unit is not for US. How can I verify whether a particular camera is for the US market or not (based on serial #, I suppose)? Thanks.
