liberace: Traveling with 2 camera's and a lot of lenses in a third world country is almost suicide. It would be better to give advice how a amateur photographer can make tacceptable photo's with the most simple equipment.
Hello liberacethanks for your comment. I have had the same problem for years as I trek through deserts for 8-12 days, up mountain passes of 5000m and more. I do not have the luxury of "paring down" my equipment for a few days and pick it up again later. A DSLR with even just 2 lenses (= 3 kg) is too heavy for lugging it around for 8-10 hours in addition to the other travel necessities (Canon full format with 28-70mm f 2.8 and 100-400mm f4). So I was pleased when the Four Thirds cameras came out and I decided on the Panasonic GH1 with a 14-140mm lens (28-280 equivalent). it's obviously a quality compromise, but at 2 kg less and readily handy slung around my neck, I have been pleased with it for the last five trips.
