I've been pondering about the 'perfect' travel kit as well as of late. For me, I think, it would be something like this:
- 10-24 (or maybe the Fuji 14 in stead)
- 35
- 55-200
- one of Fuji's mid-range zooms
I currently use the XC 16-50 and 50-230 (both terrific value for money), but might switch the 50-230 for a 55-200. It has a faster max aperture, so this could double as a nice portrait lens in stead of the 60 which is a very slow focuser. I would only get the 60 if you're interested in macro. Apart from the zooms I also have the 35 (love everything about it) and the 18 (not sure if I'll keep that one). I used to have the 27 but sold it because f2.8 is too slow in low light. I still miss something on the wide end though. Very much in doubt between the 10-24 and the 14. The range and OIS of the 10-24 are appealing, but the size/weight/faster max aperture of the 14 also seem very interesting. And the 14 has the same filter size as the 16-50 (and 18-55 and 50-230)... And then there's the Samyang 12mm as an outside contender. First world problem really, init?
