Fujifilm has added more user-interface refinements to its X100 large sensor camera with firmware v1.20. The latest firmware allows the Raw button to be user-customized. It also makes it easier to set up the camera's Auto ISO behavior and built-in ND filter. The update also claims to improve AE and AF performance when shooting movies. A PDF addendum to the user manual has also been released.

Functions that can be applied to the Raw button include:

 • Raw  • Depth of Field Preview
 • Self-Timer  • ISO
 • Image Size  • Image Quality
 • Dynamic Range  • Film Simulation
 • ND Filter  • AF Move
 • Movie  • Select Custom Setting
