The X-E4 is now a really great alternative also. If you want to shoot raw and use Capture One to process your images the 50R will be very satisfying. The 50R is definitely everything it is 'cracked up to be', you will not regret getting it, maybe you can find a used one.
I have used a XT3 for several years and loved it but my XT4 I have fallen out of love with. It keeps jumping out of automatic focus, so the indicator in the top right corner changes constantly to manual focus. that means I have to check and change it back to auto focus every shot or miss that perfect moment. I had two horses galloping towards me this morning, took a few shots and they were all out of focus because it had changed to manual focus. I have run through the settings comparing it with the Xt3 and they seem to be the same, but it is not working the same. Any ideas would be welcome.
