Carrying equip: Lowepro #? , roughly 50 x35x 25 cm (20"x12"x10"), shoulder bag (Nat.Geography)
Camera equip: Sinar P1 8x10 with front multipurpose standard long legs, Schneider Symmar-S 5,6/240, Nikkor-M 9/300, Apo-Nikkor 9/360, Apo-Nikkor 9/480, Apo-Nikkor 11/760, Sinar bihind the lens shutter, 1 extra 4X5 bellows, extra multipurpose standard, four rails (30 cm ,12"), Lee filter holder with bellows, Lee filters, loupe, dark cloth, Seconic L-608, 10 8x10 film holders, Sinar panorama head with rail holder, simple monopod with extra rail holder (for extra stability with long bellows), Kern tripod, or Schiansky mod 131.
So, how to deal with this? Well no optimal solution, but 2 alternative that I have used:
Alt 1: Rear holder, front standard and 1-2 rails on tripod with head and rail holder; in the lowepro: filmback with frame and standard 8x10 bellows, Symmar 240, Apo-Nikkor 360 and 480, Sinar shutter, extra 1-2 rails, and the rest of small things together with 2 film holders; occasionally, shoulder bag with more film holders, coffee and sandwich.
Allt 2: Rear holder, front standard and 1-2 rails on the tripod with head and rail holder; in the back pack: film back with frame and standard 8x10 bellows, Nikkor-M 300, Apo-Nikkor 760, Sinar shutter, and the rest of small things together with 2 film holders and occasionally the monopad with rail holder; in shoulder bag: extra bellows and extra multipurpose front standard, more film holders, (hopefully coffee and sandwich).
Not tried alternative: get yourself a bigger and better backpack! Like this alternative, but haven't made up my mind how big.
