Sony expands its Camera Authenticity Solution in a firmware update for the a1 II, a1, and a9 III

DPReview News

Sony announced its first firmware update of the new year, bringing changes to the a9 III (Ver. 3.00), a1 (Ver. 3.00) and a1 II (Ver. 2.00). The bulk of the update surrounds various shooting, movie and transfer functions of the three camera models. Perhaps more significant is the update to Sony's Camera Authenticity Solution, which aims to improve the implementation of the Coalition for Content Provenance and Authenticity (C2PA). The update will be available sometime in January 2025, though Sony didn't provide a specific date. You can check the status of the firmware availability on Sony's downloads page.

Camera Authenticity Solution updates

Sony is a member of the C2PA Steering Committee, playing a leading role in developing and implementing industry standards for digital content verification. As we all know, there are growing concerns with image manipulation and AI imagery, resulting in misinformation. The C2PA aims to provide publishers, creators and consumers with "flexible ways to understand the authenticity, and provenance of different types of media," according to a press release in March 2024.

Sony says that the latest firmware update expands the Camera Authenticity Solution compatibility with the a9 III, a1 and a1 II with the launch of an Image Validation Site and the Digital Signature Upgrade license developed for select news organizations and their staff photographers.

Sony says this "service is designed to enhance the implementation of C2PA (Coalition for Content Provenance and Authenticity), particularly within the news industry, by providing additional authenticity information and introducing a streamlined workflow for professionals requiring higher content verification standards." The expanded initiative will allow photographers to add digital signatures to their images, which allows for confirmation that the photographs haven't been tampered with.

Sony had previously only made this feature (on the a1, a7S III and a7IV) available to select news agencies, with a promise to expand it at a later date. It's slightly unclear from the current wording whether it's now more broadly available.

Sony a9 III Ver. 3.00 firmware update

The a9 III is the only camera of the three to receive a completely new function. With the Ver. 3.00 update, there will be a newly added option to use shutter speeds up to 1/80000 seconds at all aperture values when the Exposure Value Expand function is set to "On." This feature will be most helpful for sports and action photographers shooting at wide apertures in bright conditions.

The a9 III will see updated support for the Focus Magnifier and Auto Magnifier in MF in Bright Monitoring mode, making it easier to get precise focus in tricky lighting situations. Additionally, Sony says that users should see an improvement in image quality when applying user LUTs. There are also updates to the notification display when the latest software is available, an update to "scheduling of FTP transfers while writing data to the camera's storage media" and "improved operability including continued shooting during image transfer to the Creators' app."

Sony a1 Ver. 3.00 firmware update

The Sony a1 doesn't get any new features, but gets quite a few updates to existing features. First, it will see an update to focus bracketing support for continuous shooting while automatically shifting the focus position. Sony says there will be additional settings for exposure value adjustments and the number of shots in exposure bracketing. It will also see the same updates as the a9 III to the Focus Magnifier and Auto Magnifier usability.

Also like the a9 III, the a1 will see updates to new software notifications, FTP transfer scheduling, and continued shooting during image transfer. It will also have an update on the "use of the Custom Key settings on the AEL button and Delete button during playback."

Sony a1 II Ver. 2.00 firmware update

The a1 II sees the least updates of the three cameras, with no new features available and only a single function updated. With this firmware update, Sony promises an improvement in image quality when applying user LUTs, just like the a9 III.
