If you could bring one camera setup with you around the entire world in a year or two, what camera would it be? You can also bring four lenses. In this scenario, money is no object.
State your reasons why too.
At this moment, I'd personally bring (if only I could afford it):
--Nikon AF-S nikkor 14-24mm f/2.8G ED
--Nikon AF-S nikkor 24-70mm f/2.8G ED
--Nikon AF-S nikkor 80-400mm f/4.5-5.6G ED VR
--Nikon AF DC nikkor 135mm f/2 D
In my opinion, it'd cover all focal lengths I'd need and the defocus control lens would be great for portraits and smaller details on the trip.
What's your setup? GO!
