Today, as scheduled, Fuji has released the firmware updates for X-Series interchangeable-lens cameras. In the case of the X-E2 and X-T1 the improvements are significant, especially so with the X-T1 which now gets a high-speed electronic shutter with a maximum speed of 1/32000s. By comparison, the mechical shutter tops out at 1/4000s and this can often be too slow to take full advantage of faster lenses such as the f/1.2 56mm Fujinon in bright conditions.
Among the other goodies (there are 27 items altogether) doled out to X-T1 owners include a Classic Chrome film simulation mode, natural live view, AF+MF hybrid focusing, direct selection of macro, Q-menu customisation, new video frame rates, and tethering support
