Per a PetaPixel article, Fuji's recent firmware upgrade for the X100 reportedly improves AF significantly. There's a video link as well: http://petapixel.com/2013/10/19/fuji-delivers-major-firmware-update-x100-adds-faster-af-focus-peaking/ Link to firmware downloads on Fuji site: http://www.fujifilm.com/support/digital_cameras/software/ It's often amusing and occasionally even informative to read comments on these articles. On Facebook there are a few snarky jabs at Canon and Nikon over their perceived failure to respond to customer complaints. I don't know about Canon but as a longtime Nikonista I would say that Nikon often seems a bit aloof and unresponsive to specific types of customer complaints, and even to constructive specific suggestions about improving products. (And, nope, I'm not referring to the D600 oil shower kerfluffle, or even the alleged D7000 AF gripes.) Shall I wax tediously about the Nikon 1 System again, and how even those of us who enjoy the cameras are a bit disappointed by Nikon's inability to grok the market as well as the much more savvy folks at Sony? Nah, let's not. Anyway, good on ya, Fuji.
