Medium format, 50mm FLE, 150mm, 2x extender, cable release, carbon fiber tripod with ball head, my trusty spot meter, 18% gray card, yellow, light orange & light green filters, enough Delta 400 film and my camera backpack. Also a Gortex shell and comfortable shoes. That covers most of my photographic situations and although heavy is still manageable for me. I carry a smaller empty daypack in my luggage for occasions that the larger backpack would be in the way.

For great companionship - my wife (who speaks four languages).
