I'm planning on going travelling for 3-4months sometime next year. I haven't locked in our destinations, but trip will probably include nepal, south east asia, eastern or central europe. I plan on doing some trekking in nepal. I plan on selling my canon 600d and lenses, switching over to m4/3rds with the OMD. Mainly for the savings in weight and size. I'm also hoping the OMD with a smallish lens will be less obtrusive and tempting for thieves. What set of lenses set up would you recommend I get for travelling? Any additional gear? Assuming a budget around $1500 for lenses. Here is what I am thinking; -panasonic 12-35mm; walk around lens, f2.8 suitable for lowish light. Weather sealed to go with the OMD. Will probably sit on my camera most the time. Some cons; seems like relatively large lens. Also a little shorter in focal length than what I would prefer for a walkaround lens. -olympus 40-150mm; I don't expect to be using the telephoto range that much, but I figure it might be good to have. they seem to go pretty cheap second hand (I recently saw one sold on ebay for $100). Probably use it for wild life, maybe candids of strangers from further away, landscape when I want to get closer views of mountains/peaks. -olympus 45mm; to be used for low light and portraits. (I find f2.8 probably won't cut it in true low light situations.) Doesn't look too large, hopefully attracts less attention than the other larger lenses. Ideally I'd like something like the panasonic 20mm; the pancake size is great, I like the focal length, wide aperture. I can live with the slower autofocus, however the reported banding at high iso isn't going to make it suitable as my small low light prime, hence the 45mm. I've also given thought to the panasonic 25mm, but it seems larger than most other primes, and I'd like at least one of my lens to be small and unobtrusive. I've never shot with an UWA lens, but I like other people's photos taken with them. Unless I forgoe the 12-35mm, I don't think my budget is going to stretch for an UWA, and I don't know if my own skills are going to be able to make the most of it. I already have an ultrapod II which I plan on bringing. I'm also planning on buying a polarising filter for the 12-35mm. Not sure about GND or ND filters. I've never used them before and I'm not sure if I'm going have the time and patience to set them up properly. Also without a proper tripod, my composition is going to be affected by what I can do with the ultrapod.
