Tempted to sell my x-t20 to get this. I find the viewfinder awkward on the x-t20. Seems the main differences are x-t20 has adjustable screen and built in flash x-e3 has Bluetooth (real-time GPS tagging phone mobile)and extended iso and bracket modes. Smaller but flash is not built in( one included in the box) Doing the Inca trail next year so also looking to get an rx100m5 when a good deal turns up
I have Fujis with and without and whilst I like having the feature, I rarely use it. A quality EVF has become far more useful to me. A T20 may meet your needs.
Looks like a decent camera. Shame no articulating screen otherwise would have been tempted.
