I live in US and I want to purchase the black GM1 or GX7 from Canada either from Henrys or Adens, etc. Will I be okay shooting and editing video in the US with a camera bought in Canada? Are there any differences between the US and Canada versions of the cameras? Are they exactly the same except for the colorway options? (Canada has the cameras in full black) Sorry I am not familiar with anything related NTSC/PAL other than the fact that I know PAL is not US. And I've never purchased any audio video products outside the US.
