Currently, I am using a pair of bags. In my walkabout bag (actually a "butt-bag"), I have a Ca 1979 well-worn, black F2 (meter-less) with a 50mm F1.4 Ais Nikkor and a 28mm F2 Ais Nikkor. This is a kit that is always with me. My Domke F2 (used when I am out for the day shooting, or off exploring/travelling) contains (currently) the following: F6 and F3HP bodies and 24mm F2, 35mm F1.4, 50mm F1.2, 85mm F1.4, 180mm F2.8 ED (all Ais) as well as a 80-200mm D ED F2.8 AFS lens. The F6 will generally be loaded with E100G while the F3HP with have Tri-X/HP5 Plus. If I am backpacking/hiking, the Domke F2 will be replaced with a Lowepro backpack containing two bodies (two of: F2AS/F3HP/F4e/F5/F6) the 28-70mm F2.8 ED AFS, 80-200mm F2.8 D ED AFS, 300mm F2.8 ED or 400mm F3.5ED and the 600mm F4 ED ( as well as my surrogate Sherpa, a monstrous and unwieldy Manfrotto tripod). Needless to say, every kit has the obligatory cleaning equipment!
