Update: Fujifilm also released firmware update version 3.70 for X-Pro1.
Fujifilm X-Pro2 Firmware Version 2.00 Key Features:
1. The new autofocus algorithm* that is implemented on the FUJIFILM X-T2 will also be implemented on the FUJIFILM X-Pro2. As a result, more accurate autofocus is now possible, and the AF tracking in AF-C mode will be improved. The number of focus point will be increased from 77 to 91 points (13×7) and from 273 to 325 points (25×13) to improve framing.
* Excludes the new AF-C Custom Settings functions.
2. Compatibility with the new hot-shoe mount flash EF-X500 will enable wireless multi-flash lighting with TTL control up to three groups and high-speed flash sync.
3. AUTO POWER OFF will now have 15 sec, 30 sec, and 1 min. options. AUTO POWER SAVE function, which was previously only available in ECONOMY mode, is now available as an option in HIGH PERFORMANCE and STANDARD modes to allow users to minimize battery power consumption.
4. AF point position interlocked with parallax will be displayed to provide a more accurate and easier-to-use Optical Viewfinder even when Corrected AF frame function is set to OFF.
