Hi All, As I travel between Asia, Europe often I am curious as to if there are any differences between D4s models sold in these locations. Can anyone advise? I know that there Warranty for the Asian model will not be honoured in the UK or Europe and vise versa. This is not an issue. The model in HK is 2/3rd the UK cost! If there is no difference then I think that's the way I shall buy. My concerns are that there are differences in the software, firmware, or compatibilities with accessories ie flashes lenses. Please can anyone advise? Thanks
