I have an x100VI with 1.01 firmware - did a reset already and didnt solve issue I am about to describe. Can you all see if your camera does this: Switch to C mode, step down to f16 and then press shutter half way. Does your screen go dark? I have tried playing will all settings (have had the following so quite familiar with the menus: x100, x100f, XT-2, X-Pro 2, XT-3) , only happens in C mode. If you find this can you report to Fuji @ digitalinfo@fujifilm.com. They told me they had not seen this before and that it was normal behavior because the shutter is closing, but the shutter closes in S mode as well.
