X100 UNDERexposure fault
This evening for some reason my camera would not shift from 1/4000s to A for aperture priority. 1/4000s was persistent and M for manual was showing on the LCD. This went on for some time. Maybe some grit under the shutter speed dial? It works most of the time now. Haven't dropped it for months, and certainly no moisture near it. Lately it's always in the never-ready case. Although it is not meant to be capable of this, I have some images whose exif data records 1/4000s at f2 with underexposure probably consistent with that.
