Content Authenticity For The Sony A7 IV

credits: Sony

Sony just rolled out Firmware Ver. 5.00 for the a7 IV, adding a feature that lets photographers attach a digital signature to their images—basically proving they’re real and not AI-generated. This Content Authenticity Solution was previously only available on Sony’s top-tier cameras like the a1 II, a1, and a9 III, but now it’s making its way to more affordable models.

With all the AI-generated images and deepfakes floating around, having a built-in authenticity tool is a big deal. But there’s a catch: it requires a paid license and is only available to certain media outlets—regular users can’t access it (yet). Sony hasn’t said when, or if, that’ll change.

Still, the fact that they’re adding this to more cameras is a good sign. If Sony ever opens it up to the public, the a7 IV (and likely other models) will already have it built in and ready to go.
