Although a little late, a good review.
I've had my X-T1 since March, and while I do enjoy it, selecting AF points is a chore, especially vs. touchscreens. I don't the same issues with the rear directional buttons or dial that others have lamented, and I haven't shot any video yet, but I do find adjusting the controls to be a bit fiddly on the fly.
That said, with the recently released XL hand grip and eyecup, handling is much improved. Moreover, I absolutely love the aperture ring, as well as the overall build quality. I also enjoy the huge EVF, but I've read that lowlight reveals it's weaknesses.
Regarding the chromatic aberration, there is an in-camera lens correction option that removes CA, and perhaps barrel distortion, from images shot with Fuji lenses. It's apparently quite competent, but I've not used it, as the 18-55mm f2.8-4 has produced excellent RAW captures as is.
Finally, however, for those uninterested in the retro aesthetic, Olympus' OMD-EM1 (the X-T1's main competitor IMV) is perhaps a better choice; its in-body 5-axis image stabilization is apparently the best available, its touchscreen and customization features are very useful, and its EVF is also quite large. Moreover, its build quality is supposedly a tad better, and its AF is excellent. Micro 4/3 lenses offer greater selection at often lower prices, although some may balk at the smaller sensor.
Personally, as much as I do enjoy my X-T1, I'd love to try out the EM1 for a weekend.
