Sony releases new Alpha camera firmware updates including C2PA Compliancy to authenticate images

Sony has recently released the highly anticipated firmware updates for the Alpha 1 (Ver. 2.00), Alpha 7S III (Ver. 3.00), Alpha 7 IV (Ver. 3.00), and after April 2024, the Alpha 9 III (Ver.2.00). The update contains some of Sony’s most impactful technology, including Camera Authenticity Solution, the proprietary in-camera digital signature and C2PA (Coalition for Content Provenance and Authenticity) format support. Together, these tools will make it possible for news agencies to ensure the authenticity of images, contributing to industry efforts to protect creators, and society from fake imagery.

Additionally, the firmware updates include many requested features to improve everyday use. The update evolves shooting functions and post-shooting workflow and brings advanced movie features like breathing compensation. It also includes new remote-control capabilities, new features for professional applications, and expanded access to cloud services applications.

Camera Authenticity Solution

Last year, Sony announced its commitment to developing technology in its cameras to aid in the fight against manipulated imagery and AI-generated fakes. The severity of this issue is only increasing and it’s a complex problem that requires the focus and attention of our entire industry.

One critical part of the solution is making more Sony cameras C2PA compliant. C2PA is a Joint Development Foundation project, where Sony is a steering committee member. C2PA aims to develop an end-to-end open technical standard to provide publishers, creators and consumers with opt-in, flexible ways to understand the authenticity, and provenance of different types of media. The C2PA is a standards-setting body that will develop technical specifications on content provenance and authentication by certifying the source and history of media content. With this firmware update, the authenticity information embedded on images from Alpha 1, Alpha 9 III, Alpha 7S III, and Alpha 7 IV can be maintained from capture through publication. This provides professional photographers with the ability to preserve their digital signature from the camera, while tracking the editing history throughout revisions.

Another critical component of the solution is Sony’s in-camera digital signature technology that signs images in real-time. This new feature certifies the authenticity of an image at the point of capture and creates a ‘digital birth certificate’ that is retained throughout revisions. The signature contains metadata including 3D-depth information captured through the proprietary technology in the image sensor developed by Sony. This depth information can show if the image captured was of an actual 3D object, vs a photograph of an image or video, providing an extra level of protection and even more assurance of the content’s authenticity, and making Sony’s solution especially unique for photojournalists and news agencies.

Sony’s solution also helps protect the authenticity of content by including an Image Validation Site, which verifies the image even after edits have been made by C2PA-compliant editing software. This service confirms the authenticity of the photo was taken by a specific camera and that the object of the photo is 3D. This service will initially be offered to select news media agencies, expanding to other agencies at a later date.

Shooting and Playback Updates

The firmware updates include over 10 new features, as well as improvements to existing features, designed to improve the user’s overall shooting experience. These improved capabilities showcase Sony’s commitment to continuing to evolve the functionality of Sony’s existing camera models. A few highlights of the firmware update functions include:

• Relay Playback: Enables seamless sequential playback from one memory card slot to another on the Alpha 1, Alpha 7S III, and Alpha 9 III.
• Playback Filter Condition: Lets users categorise image playback based on select criteria including date, folder, file format, and more on the Alpha 1 and Alpha 7S III.
• Breathing Compensation: The highly requested Breathing Compensation function is now available on the Alpha 1 and Alpha 7S III. 
• Upgrade DCI 4K / 24.00p Upgrade License on Alpha 7S III: via a free downloadable license through Creators’ Cloud.
• Sync Release function: Enables simultaneous shutter release with two or more multiple cameras connected to the main camera on the Alpha 1 and Alpha 9 III.
• Focus frame display: Focus frame will be displayed on the Remote Camera Tool screen³ on the Alpha 1 and Alpha 9 III.  
• Enhanced image stabilisation: The camera body and lens effectively work together to correct larger blurs on the Alpha 1.
• Increased upper limit of recordable images in a folder from 4,000 to 9,999 on the Alpha 1, Alpha 7S III, A7 IV, and Alpha 9 III.
• Matching the time code with other devices is now possible with a dedicated adapter cable (sold separately) on the Alpha 1 and Alpha 7S III. 
• Up to 20 IPTC presets can be on the Alpha 1 and Alpha 7S III.

File Transfer and Network Connectivity 

Additional updates aimed to optimise the post-production workflow efficiency include improvements to International Press Telecommunications Council (IPTC) preset and File Transfer Protocol (FTP) transfer operability. To streamline processes for users, expanded cloud upload and application services will be available. Key updates include:

• Cloud upload (camera direct) function allows users to upload images directly to the Sony’s Creators’ Cloud. Key additional features include simplified camera software updates, direct camera registration to the Creators’ Cloud, and a flexible system for uploading, storing, and sharing content. Additionally, the capability to manage video and LUT files via mobile apps, along with the transfer of RAW files to smartphones, optimises the creative process in fast-paced environments.
• FTP Transfer Improvements: A “Protected Images Only” option for the Auto FTP Transfer and a “Protect Image in FTP Transfer” option for the FTP transfer function have been added. Available on the Alpha 1, Alpha 7S III, and Alpha 9 III.
• Support for USB streaming on the Alpha 1. 
• Secure File Transfer Protocol (SFTP) has been added to secure protocol on the Alpha 1, Alpha 7S III, and Alpha 9 III and WPA3-SAE is now supported for wireless LAN on the Alpha 1 and Alpha 7S III.
• Network streaming enables direct live streaming from the Alpha 7 IV to a streaming site. 
• Expansion of app support with Creators’ App and Monitor & Control app now supported with the Alpha 1 and Alpha 7S III.

Many of these updates are applicable to multiple cameras, however for a list of each body’s specific update please check the Sony website.
