I apologize if I am in the wrong area for this, but I am currently pricing this camera, and sometimes I come across someone selling Canon EOS 1D Mark III Body (Jap/Eng). I have seen this camera about $300 cheaper than the US version. My question is, what is the difference? Will the camera have the same functions as US, but in Japanese language, or default Japanese language that can be viewed in English? Thanks in advance for any help.
