I can't say that I have any issues with my Fujifilm camera bodies, but my primary reason for my switch to Fuji where the lenses. Continuous autofocus was actually so bad that I bought a Nikon D7200 just for the sake of shooting actions. With the X-T2 things have improved, but not to the extent that it can replace my Nikon with the long telephoto lenses. Except for autofocus I love the gears and I don't think I will change it in the nearest future. However there are a few things I would love to see in a coming camera like built in image stabilisation and a real implementation of back focus (AF-ON). Improved battery life is also on my wish list.
So yes, I can live with the camera bodies, because no one else have a lens collection that can beat Fuji.
