Hi everyone. I am having the same annoying issue with the Fuji X-Pro2, using the 35mm 1.4 lens. I have had four photoshootings with it so far and it is a pain in the ass when you get interrupted that way. This issue occurred reliably all the four times I used the camera, I was always shooting without a flash. My SD Card is a Lexar Professional 633x, 32GB, 95MB/s. I have a feeling it only happens when I am using the electronic viewfinder (which I used most of the time). With the optical I did not yet experience it, as far as I remember. For that reason I think it is rather a software issue. Hopefully...
I called the german support and the lady on the phone said she did not yet hear of this problem and that I should send it in. Definitely not what I wanted to hear... I will double check shooting with the optical viewfinder and I will also try the kit lens that came with my good old x-e1 instead of the 35mm lens.
My Serial number is 61U05XXX
