In reply to MrRiley:
I had Fuji X100F and was quite disappointed. Lots of people are saying it's build as a tank due to the Made in Japan label. The EVF/OVF shutter broke less than in 6 months, quite few people experience shutter button coming off, especially when using with the threaded soft release shutter button. I was lucky I had warranty still as the repair is quite pricey (one of the forums mentioned £580 for the exact same issue: https://www.fujix-forum.com/threads/how-much-to-fix.18712/ , but third-party service quoted £178).
I am back to M43 and Panasonic GX80/GX85 with Panasonic 20mm F/1.7 pancake is not much bigger. While 35mm is great for all-round photography in the hills, I can now choose from Pana 20mm F/1.7 pancake, Sigma 60mm F/2.8 short-tele, Pana 35-100mm F/4.0-5.6 as small tele and Pana-Leica 10-18mm F2.8-F4.0 as wide lens.
I treated X100F as a baby. I am now less afraid of getting the camera covered in ice (happened with different M43 body), throwing it around and abuse it occasionally. It's camera I use in the mountains, after all.
My point? X100F is regarded as a tank, but XF10 would be a downgraded version of their APS-C fixed primes (they also had X70 fixed prime and X30 fixed zoom). Maybe I was unlucky, but after reading up, they do have problems. All cameras do, but they do not carry a premium price tag.
