A free firmware update for alpha 7 II cameras is scheduled for November 18. It will add uncompressed 14-Bit RAW image capture and activates phase detection AF for faster and more precise autofocus with lenses designed for interchangeable-lens cameras.
The alpha 7 II becomes the latest Sony full-frame camera to offer uncompressed RAW capture, which becomes a selectable feature (uncompressed/compressed RAW) within the menu system.
It becomes the second Sony camera to offer fully-functional phase detection AF to A-mount lenses in addition to E-mount lenses. The firmware update activates the 117-point focal plane phase detection AF sensor on the camera for lenses beyond just the native Sony FE lenses. This includes Sony’s A-mount lenses, which can be utilized along with the LA-EA3 mount adapter.
In addition to these feature upgrades, the Movie button can now be assigned to a custom button.
