Published: March 27, 2024


Sony releases more than 45 Firmware Updates for Alpha 1, Alpha 7S III & Alpha 7 IV cameras to improve Shooting Functions, Workflow and C2PA Compliancy to Ensure Authenticity of Images. Additionally, Sony announces an upcoming Sony Alpha 9 III FW update.

SAN DIEGO, March 27, 2024 – Today, Sony Electronics delivers 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 support1. 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.

“There is nothing more core to our mission than listening to the voices of the photographers, videographers, and filmmakers who shoot with Sony Alpha cameras. We know this community has been asking for these updates, and we’re happy to deliver. Each of these updates are designed to promote ease of use for our creators and allow them to maximize the strengths of their cameras,” says Yang Cheng, Vice President, Imaging Solutions, Sony Electronics Inc. “We’re especially pleased to deliver C2PA compliancy with this update. This compliancy paired with our unique digital signature technology, allows us to offer the most secure and comprehensive solution to protect professional photographers, news agencies, and society from manipulated imagery.”

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 technology2 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 categorize 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 function3 is now available on the Alpha 1 and Alpha 7S III.

Focus frame display: Focus frame will be displayed on the Remote Camera Tool screen on the Alpha 1 and Alpha 9 III. ​

• Matching the time code with other devices is now possible with a dedicated adapter cable (sold separately)7 on the Alpha 1 and Alpha 7S III.
Up to 20 IPTC presets can be on the Alpha 1 and Alpha 7S III.
Custom Grid Line is available as a paid license basis for some models8.

File Transfer and Network Connectivity

Additional updates aimed to optimize 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’ Cloud9. 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, optimizes 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 streaming10 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 site7.

    1. Sony a7R V is the current version of that camera.
      Aside from possible bug fixes or compatibility updates, don’t expect any firmware updates for a7R IV or a7R IVA.

  1. A long read but understandable! A reason I went Sony in ’14 is Canon had no more updates for my T2i as well it disappeared from its site in a effort to sell the newer models. It is great Sony is keeping it’s models up to date with user wants.
    But an issue that really bothers me, The Sony A7M2 still sells new as a great starter camera, has IBIS and before other makers as well of many other things, But again somethings that Mod 1’s and 2’s have the ability to have and that is on camera apps downloaded from sony playmemories apps – . Right now even if someone buys a new out of the box A7M2 that person probably will never hear about the apps like most even representatives never heard of, I was in a Best Buy and I told a rep about them then went and bought one after I showed them on my A7RM2 and now the site is turned off for buying and will in a year be gone.
    I have been a part of the Sony growth since the beginning and know the older cameras will be around for a long time and Brian Smith still has Books (today PDF’s) filled with info on the uses. I downloaded all the apps to my Mod 1’s and 2’s. The mod 1’s and 2’s will be on the used market for a long time and great starter cameras and the apps are great to play with for a first time camera owner used or new.
    Not a social media person but the apps like the Digital Filter is great to have, a little slow but great results and no need to carry a bunch of filters around.
    My point to Sony is that digital cameras like the old film cameras are forever like camera lenses will be around forever. So if a person wants to start playing with photography a low cost used camera will get users to be Sony members bragging to others meaning possible future sells. It is like the old film cameras are on a comeback and film is being made 24/7 again.
    Sorry to be long winded about this issue but I had a door slammed in my face once and I just feel others should be able to get on the Sony train for there are more tracks to future cameras and lenses.
