Just weighed the 5x7 kit I am taking to the mountains tomorrow.
Linhof 5x7
Pentax Spotmeter
Filters
Metal Lens Hood
7-5x7 Holders
210mm Nikon Lens
120mm Nikon Lens
Dark Cloth
Cable Release
Measuring Tape
Backpack
Odds and Ends
Weighs 15.5 Pounds
Metal Tripod
Geared Head
Weighs 6.5 Pounds
My total kit in the field for walking or wheeling (the backpack has straps or wheels) weighs 22 pounds.
This trip and this equipment is a trial run for making photos in Thailand. I am not sure I can transport this much gear in the Thai heat. For doing the 5x7 or possible 8x10 portraiture in Thailand/Cambodia/Laos etc I might have to design and have built (in Thailand where it is cheaper) some kind of folding push/pull cart to carry everything.
