Sony has released firmware version 1.10 for the Sony a9, bringing improved image quality to the camera alongside a bug fix that addresses a problem with Raw images disappearing when SDXC and microSDXC cards were transferred from the camera to ‘certain smartphones.’ The update also adds the Eye AF function for some A-mount lenses when they’re used with the LA-EA3 mount adapter.
Firmware Version 1.10 for the Sony a9 is available to download from Sony’s website.
