Sony’s PMW-F5 and PMW-F55 cameras get their first upgrade of the year with today’s release of v9.0 firmware. The new update adds new frame rates for 4K raw and 4K X-OCN recordings to the AXS-R7 recorder, a “Parallel Rec” mode using the CBK-WA100 wireless adapter that synchronizes the camera recording with an XAVC Proxy file with the same file name, and XAVC HD Long recording and playback.

Also new in the update: remote iris control is now smoother, vertical noise has been removed from dark areas in 120fps 4K recordings to the AXS-R7 recorder, clip-name metadata is now embedded via SDI output when recording to the AXS, and a bug has been fixed related to dropped frames in certain slow-and-quick motion recording modes.

Sony cautioned that users should not immediately attempt to upgrade their cameras to v9.0 if they are not currently on v8.0. Posting to the company’s community forums, Sony’s Peter Crithary specified ranges of serial numbers that may not be user-upgradeable and require help from a local Sony Service Center.

Sony detailed all of the changes in published release notes for the new firmware.
