My camera bag includes:
Nikon D3x body,
Nikon 300mm F/2.8,
Nikon 600mm F/4,
Nikon 2x and 1.4x Teleconverters,
Nikon 200mm F/4 Micro Nikkor (macro)
Nikon 50mm F/1.4 Manual Focus
Gitzo carbon fibre tripod with Jobu BWG PRO gimbal (mark2).
In hiking mode, the kit is carried on a Scopac. Circular polariser and neutral density (ND2) filters are also used when conditions demand them. I carry about 32 gigs of memory on two separate cards and I generally shoot in RAW. Nikon Capture NX2 is used to process the images. If space and weight allows on foreign trips, I take my laptop and download all images each evening. My favourite bins are the new Nikon EDG 8x32.
