I got my X-Pro2 at the beginning of March and after a month and some shootings I want to share the issues I had before updating the camera with the new firmware. I'm using the camera with these lenses: 35mm f/2, 18-55mm 2,8-4 and 56mm f/1,4
1. Reset settings issue: it happened the same day I bought the camera and after recharging the battery properly no more problems so far
2. "Turn off the camera and turn it back on" message: using the 18-55 F/2,8-4
3. Overheating under various situations: mostly using the 18-55 f/2,8-4
4. Camera unexpectably freezing under random conditions: using the 18-55 f/2,8-4
5. Wi-Fi lock-up: it takes a very long time, it can get disconnected very easily and than no way to reconnect: the camera just doesn't recognize the device anymore (iPhone or Instax printer)
6. AF speed: not that fast compared to my previous XT1. Sometimes it doesn't lock at all even in good light conditions
7. Unexpected and strong underexposure (about 1 or 2 stops under): I was using the EVF and the center weighted metering mode and everything seemed ok even reviewing the images. The problem came up when I opened them in LR. In another thread here some users shared infos about this issue and it seems to be caused by incorrect LR RAW processing when the AUTO DR is on.
About the lenses I use, whilst I did not have any problems with the 35mm f/2 and 56mm f/1,4, all the issues I encountered happened mostly with the 18-55mm, which, by the way, sometimes starts focussing unceasingly and I have to turn the camera off and than on or, when this operation isn't enough, I have to remove the battery.
So fingers crossed until Fuji will release next firmware and Adobe will fix the Fuji RAW processing in LR...
