Fuji released today the 1.11 firmware update for the X100 camera. I had this FW for a week or so already and do not notice much of a difference in regards to AF speed. To check what firmware you are running on your X100, turn on the power while holding down the “BACK” button. To do a quick update all you have to do is download it HERE, save it to your desktop, drag it to a formatted clean SD card, insert card into the camera and turn on while holding the “back” button. Then follow the on screen instructions.
Improves AF performance in the macro range,
and fixes two bugs:
I) When “SHADW TONE” is set to “MEDIUM SOFT” or “SOFT”, solarisation may occur on the LCD just after pressing the shutter halfway.
II) With the self-timer activated, focus and exposure are set just after pressing the shutter release and these settings remain locked until the shutter is released
