Sony have released new firmware for their high-end F5 and F55 cameras, bringing them to version 6. There are several bug fixes and improvements, with the headline change being the ability to record ProRes 4444 in-camera (for owners who have already paid Sony to upgrade their cameras to record ProRes at all).
   

Users on the Sony forum don’t seem that impressed – and indeed this release doesn’t fix long-standing niggles like not being able to manually white balance in any of the Slog modes; there’s also still no way of having the 2K centre crop assigned to a programmable button.

Still it’s probably a good idea to keep your camera up to date, you can download the latest F5/F55 firmware at Sony's site.
