Coming from the X-T10, I decided to go for the X-T20 over the X-T2 mainly because of the price difference. There was also a promotion here in Japan for a free MHG-XT10 grip which doubles as a permanent arca mount. For those who don't like the handling of the X-T10/20, I highly recommend the MHG-XT10, it makes a big difference. The weather sealing of the X-T2 would have been good, but since I don't have any WR lenses, I figured just go with the cheaper body and buy another lens...maybe the XF50mm F2 WR or XF56 F1.2? Opinions? I currently own the XF18-55 F2.8-F4, XF35mm F1.4, XF10-24mm F4, XC55-230 F4.5-6.7, and a Samyang 8mm F2.8. The X-T10 took wonderful pictures, but there were some things I didn't like which is why I wanted to upgrade.
I'm really impressed with the AF speed of the X-T20, and the deeper buffer was a welcome upgrade. The X-T10 buffer was a joke, but not a big issue if you don't shoot sports or wildlife. Overall I am very satisfied with the X-T20 as an upgrade to the X-T10, however, the one thing I don't like about the X-T20, or should I say, the X-Trans III sensor, is the sensor flare. If you shoot towards the sun (something I do from time to time), anything above F11 causes some nasty sensor flare - much worse than the X-T10 (X-Trans II). If this happens, you will just have to recompose or shoot at a wider aperture.
I think the X-T20 is a beast and I think anyone who buys it and learns the ins and outs of the camera will be very pleased.
