I still don't know if the camera is intended for your wife, or her boss, and who is going on the trip, and on reviewing the thread, it seems I'm not alone.
It makes a difference. We now know something about your wife's photographic experience and aspirations, but nothing about those of her boss. There is also the issue of where the ultimate recipient is going to get support (your wife from you, or her boss from her on the trip). Then there is the issue of the potential downside if indeed the camera is for her boss and it is poorly received, a situation that might best be avoided in the first place.
Any chance of a simple clarification?
Who is the camera for?
Who is going on the trip?
