Hi, I'm in central Vietnam now, in a town called Kon Tum. There seems to be a lot of colour film around (stacked up in the glass counters at photographic shops), I haven't checked it out thoroughly but a lot of the time the packaging looks faded and I haven't noticed what film it is. I'm carrying a lot of film (mainly using b&w, which I haven't seen anywhere) so I don't have to worry for a while, If I can make it to Thailand before I run out I might get more there, otherwise get some sent maybe.
As for lenses, I'm carrying CV 25 snapshot, 35 classic, and 50mm J8. In the crowds of HCMC 25mm is great because some of the time I can't get far enough away while still seeing the subject, 35mm is my 'zoom' lens (zoom by walking forward or back, a compromise a lot of the time) and works well in a range of situations, and 50mm for the more open streets and because a lot of the time I like it.
The most major piece of advice I can give is to look after your eyes (and health in general)! It seems obvious now, but in a warm and humid environment hygeine is important at more than meal times. Somewhere along the way I got an adenoviral eye infection, usually limited to outbreaks in schools etc. in the West, but more common here apparently (the doctor I went to said she'd been having a few in). It seems I could have got it from being around someone with an upper respiratory infection, from the water getting in my eyes, or from someone else with an eye infection, and rubbing my eyes with my hand might've helped it in there (actually, I've also wondered if it might've come from my camera after letting a kid look through the viewfinder).
Whatever it was, I was in a dim hotel room for two weeks with sore, light sensitive eyes, swollen eyelids, and blurry vision from corneal damage. I'm just over it now, but despite precautions my partner now has it, so more waiting.
All that being said, I think provided you take a little precaution, all the hype over health concerns isn't as big a deal as it's sometimes made out to be. So don't forget to have an amazing time! 😀
