Happend with my two months old X-T1 for the first time. Fw 4.30 with the 16/1.4 lens attached.
I took a picture, the shutter opened half way (partial "clank" sound), the evf/lcd gone black, the indicator was stuck on orange and I had to take the battery out and back again. Once the camera powered up again, the shutter finished its cycle and I could keep shooting. So far I failed to replicate it. Something tells me it will happen again soon. I'm using a UHS-II card by sandisk (280mb/s), the next time this happens I'll go back to a regular 90mb/s card and see if this eliminates that.
