I tend to look at it from a system point of view
If you already have the 10-24mm, 18-55mm then the 55-200mm lens is the best complementary lens to complete your system
These 3 lenses together give you a great travel range
I have the 135mm and had the 55-200mm too but sold it for the 50-140mm. I am happy with both lenses and my 135mm seems to be pretty sharp
I normally travel with 2 Fuji bodies (XT2 and XPRO2) plus
10-24mm
18-55mm
50-140mm plus a 1.4X converter and if my trip requires it
100-400mm as well
I just pick the lenses I need for the day and leave the rest in my hotel locked up in my suitcase
either way you can't go wrong with Fuji Lenses
All the best and have a good trip
I travel quite a bit and my XT-2 stays mostly paired up with my 18-135mm. While I do have some gripes about it's sharpness and IQ especially when racket out to 135mm. It tends to be a little soft but the lens is infamous for this.
Where this lens shines is the wide focal length range and WR. It's a day time lens so I usually have it stopped down to like f/8 and it does fine given the light is enough. It's been everywhere from the rainy muddy hills of Iceland to the Sahara desert. In these conditions the less you have to change lenses the better.
In fact the 90% of the times where I do change lenses is to put on my Samyang 12mm because 18mm just doesnt cut it for mosy landscapes. The only other lens that I carry in my travel kit is the 23mm f/1.4 for low light.
For what its worth, one of my travel buddies has a XT1 with am 18-55mm which she uses mostly and a 55-200mm which she loves, but doesn't use often as it isn't too versatile as a travel lens and finds herself taking it off just as quickly as she put it on. Could just be different styles.
Here is my travel photo blog. http://mikeo0.synology.me
Im unsure if all the EXIF data is intact, but nearly everything was shot with the 18-135mm except the obvious low light photos which were done with the 23mm.
