I have now bought a Sony NEX-5n, the new version of the Sony NEX-5.I think this will be a perfect camera for the Aconcagua expedition and all future expeditions. A camera with big possibilities but in a small form factor.
I choose the NEX-5ND, the more expensive configuration with both E16 mm f2,8 “pancake” lens with Wide angle and E18–55 mm f3,5–5,6 zoom lens.
