My congratulations to you. I reckon you have made a great choice.
I bought into Fuji (also with an XT2) in February, after years of using Nikons. I still love my D700 and D800, but the XT2 is a camera uniquely its own, with lenses renowned for their sharpness and tonal rendition.
I wanted a lighter camera than my bulky Nikon Ds and the XT2 is ideal. My goals were twofold - to get away from the somewhat static photography I've tended to do (I'm a retired architect, so for a long time I've photographed mostly buildings, in fact my most 'active' subjects for years have been rather static travel images, my partner at home and our cats, which sums up 90% of my photography for the last several decades) and do more candid/street work, also to free up my thinking about the images I make and my approach to my creative approach.
So far I'm still going through the 'learning curve' with the Fuji, and I must admit it has been slow if steady, so very different from the way my D700 and D800 did things for me. It took me a while to fine-tune the colours I want, but after exploring the possibilities offered by the XT2 I've found it's even more versatile than my Nikons. I am now more into black-and-white photography than I was before, and when I download my day's images I always marvel at the superb tones I'm now getting.
Of course lenses come into the picture. My preferred lens is the (full frame) 28mm, so I initially bought the 18/2.0, then the legendary 18-55 zoom, both of which have served me well. On an impulse I then bought a 14/2.8 which I've yet to make much use of, but intend to do more 'tight situation' photography in the near future, also a 23/1.4 which I saw in a secondhand retail shop in Melbourne and immediately fell in love with. This lens (the 23) spends more time on my XT2 than the 18, and I enjoy its flexibility, being able to move quickly from fully autofocus to entirely manual when I want to.
I'm sure you will appreciate your XT2 to the utmost when you've played a bit with it and practiced shooting your preferred subjects. You will enjoy the less vivid color rendition it gives, but I suggest you devote a little time to playing around with the black-and-white features. You will be truly surprised at your results.
Enjoy...
