I upgraded from XPRO1 via X-T1 to X-T2. I was quite exited when X-T2 was announced suggesting that is was way and way better than the X-T1
OK, one advantage is the joystick. I really don't consider AF that much faster? I don't shoot movies so can't judge that.
More megapixels means more noise. With the X-T2 I sometimes have focusing issues with my 50-140 lens which I did not have before.
So am I happy? Not that much to be honest. Overall of course The X-T2 is a very nice camera. But I regret that I sold my X-T1.
Also the differences between X-T1 and X-T2 being not significant enough (for me), have made me decide to skip the X-T3 for sure .
NB the same accounts for my upgrade from X100T to X100F. Not that different. Nice joystick, nice ISO button, but with the premium price tag these are expensive features 🙂
My previous upgrade from X100 and X100T was a real difference in speed though.
The "artistic" (ahum) quality of my shooting remains exactly the same with either XT-2 or X100F 🙂
For now I will stop upgrading for a while and focus on making pictures again 🙂
I would like Fuji to concentrate even more on improving their firmware (Kaizen, there "Unique Selling Point") than bringing out new hardware all the time
which make you feel you made a bad investment all the time buying the previous model. Their Kaizen feels more like bug-fixing nowadays 🙂
