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. The firmware can be downloaded from this link http://www.fujifilm.com/support/digital_cameras/software/firmware/x/finepix_x100/index.html

I am really impressed with the new update for X100. It really makes the AF very snappy even in low light situation. Also, it seems to me that MF is a bit faster now!!! One of the best features of the new update is assigning different functions to RAW button. I have now set RAW button for ND filter and Fn button for ISO. Really well done Fuji.
