I'm entering the water here gently, having test-driven an xA5 and 15-45pz. My main test day was very sunny, so the screen was a reflective washout; I'm returning the xA5, and an xT100 will arrive tomorrow.
Neither Xtrans nor 'retro' are big on my list - but many of the other standard features are ones that I use frequently (tipping touchscreen, usb charge, still imaging foremost). I migrated from Pentax (1980-2000 and 2017-20) with digital lately being µ43. I've a PK-fX adapter for some of the older lenses I still own, and the native 15-45 plus a TTArtisan 35/1.4 that I really liked on my micro bodies.
That's all for now - looking forward to a damp but entertaining weekend trying out the xT100! 😏
