Just received my X100V (the black model) from Adorama. Yes, it makes a noise when using the manual focus. Probably will be a problem if changing focus when shooing video. Also, disappointing that such a high priced camera has these obvious mechanical problems.
The camera seems to get pretty hot during use in the lower right back of the camera, but I assume this might be correctable via firmware. But I do not see the grinding noise being something to fix via firmware.
I regretfully will have to return this camera unless Fuji Corporate can offer a quick solution.
