And that is why he is Director of National Geographic Travel and not National Geographic Magazine

But more seriously - I do have a Sony Nex-6, which with the proper adapter (one that corrects FX lenses back to full frame on the APC sensor) will take images close to the big camera and weight at best a pound less than my DSLR with grip. All the other stuff I listed above would still be the same, leaving me with a 8+ pound photo gear anyway. Going compact doesn't save you the weight - compromising on everything else does.
