@brandonlee I've looked at the Sony's before, but they lenses are a bit slow, sensor a bit small (want at least 4/3rds, aps-c is nice).
I hadn't looked at Fujifilm before; not sure why. Both the XE3 and X100F look really interesting. There is some appeal to the X100F; I only use primes (typically 50mm) on my D750, the X100F is a bit wide. But it's so lovely and flat, and looks nice; if it had 4k video it’d be a winner. Perhaps I need to not worry about that.
The XE3 would be more appealing if there was a really flat pancake 35 or 50 (35mm equiv) lens. With the big lenses, it seems like it would become almost as awkward to carry as my D750! :)
