Thanks Trevor!
Let's see….Back on this trip I had a Nikon D80 with a Nikon 18-70 zoom and an old Nikon 70-210. I carry a Polarizer and 2 Galen Rowell Split ND filters. I also carried a Gitzo Carbon tripod and a small Benro ballhead which together weigh about 3 pounds.
I've now upgraded to a D700 and some other lenses. The D700 is a beast to carry but I love the image quality.
