Hi all,
In January I am heading off to SE Asia - my girlfriend and I are taking 8 months to travel to pretty much everywhere in that region! We always travel light, and I've done a number of 1-2 week-long backpacking trips, but never anything like 8 months....so I'm looking on advice for gear sooner rather than later 
I did 10 weeks once with my digital setup through Ireland, and the weight and pain-in-the-ass that it was made me vow to never do that again. Have since used film when traveling, no if's and's or but's about it. Girlfriend has a very nice digital P&S for when we need to have instant review, or I need to check an exposure.
The gear:
Nikon FM2n
Nikkor 20mm f/3.5 AI-S
Nikkor35mm f/1.4 AI-S
Nikkor 105mm f/2.5 AI-S
52mm circular polarizer
52mm 3-stop ND
Slik sprint pro 2 tripod
10 rolls Portra 400, 10 rolls Portra 160 (to start, I'm a very conservative shooter, a roll a day would be CRRRRAAAAZY for me). Will buy more film as we go.
Total weight: ~3kg
The considerations:
1) I'm thinking of picking up a 300mm f/4.5 AI-S since there are going to be some amazing wildlife opportunities...it adds 1kg to the weight, and a lot more size, but I think I might regret not having a focal length like that. Anyone with experience in the region have an idea on how crucial 300mm is?
2) Film. There is going to be a lot of film in my backpack after a few months. Is it risky to mail it home at regular intervals? Or should I look at getting it developed there? Any input on that matter would be super.
Other thoughts are very welcome too of course
