They just updated the firmware again and this time it is a *HUGE* improvement overall. I shoot a ton of corporate work where the likes of Clinton, Steve Jobs ( RIP ) and others are in attendance. In my 18+ years of using digital cameras, the X100 is by far the best one I have ever used in this genre, it is simply incredible and the people I photograph think I am using a Leica, LOL!
I am going to be doing a review from a "Users Perspective" on Photo.net in the coming weeks with lots of photos, for me, the X100 is an M9 killer and proves it self as being such more every day...
