My sister needs a new camera for an overseas trip, and I don't know anything about non-SLRs these days.
Cost is not especially an issue, but nothing too valuable or ostentatious (we don't want it getting stolen).
It needs to be fairly small physically, small enough for a pocket is good.
It needs a reasonably flexible zoom lens, but I think not one of those superzoom things as we don't want something too large and expensive-looking
Raw ability is not actually required but very much to be preferred.
I'd like to see it have decent higher ISO capability (so far as is possible in a P&S)
Anything else I need to mention? Brand doesn't matter, whatever is good. Tough build is good as she will be in the tropics during the monsoon season - hot, humid, rain every day. All advice welcome!
