This and the 18-55 xf make a great entry-level travel or zoom kit. Earlier this year I bought pro xf 16-55 and 50-140. Both are admittedly excellent lenses and weather resistant. But they are bigger: wider, longer and heavier. I'm past the age where I have to lug around heavy camera gear on vacation. The reviews for the lighter pair were so good that I took a chance and bought one first and then the second. The speed and quality of these lenses combined with the X-T2 is amazing. I reduced the weight by over 3 pounds and it all fit into a Think Tank Speed Devil along with a couple of refills, batteries and a charger. I also recommend a non-power grip for this kit and a power grip for larger lenses.
