I still don't leave for over a month, I'm trying to figure out what I will need.
2 Bodies (M5 for B&W film, R2A for slides and colour film)
3 Lenses (35mm f/2 Biogon, J-3, CV 21mm)
20 Rolls B&W film (deciding between TRI-X and HP5)
10 Rolls Colour film (4 rolls K64, 6 rolls Fuji 400H Pro?)
F-5XB to carry one body + film while I shoot with 2nd body
Film picker
Mini tripod
Extra Batteries
Sharpie Pen
Notebook and ink pen
Microfibre cloths to wrap lenses in
Filter wallet with filters (Yellow, Red)
All this fits in the F-5XB as long as I have one body out of the bag.
