[Update] Notice Regarding the Use of Tamron 70-180mm F/2.8 Di III VXD (Model A056) with Sony Alpha 7 V

Thank you for your continued support of Tamron products.

We previously announced on our website on January 6, 2026, an issue where the 70-180mm F/2.8 Di III VXD (Model A056) for Sony E-mount
does not function correctly when used with the Sony α7V.
While we have been addressing this issue by updating the firmware at your nearest subsidiary or distributor,
we are pleased to inform you that you can now perform the firmware update yourself.

[Important Notice]
Due to the nature of this specific phenomenon where the lens is not recognized by the Sony α7V, 
a camera body other than the α7V will be required for the update process.
We sincerely apologize for the inconvenience, but please use a different Sony camera body to perform the firmware update.

Altimately, we can still update the lens for you at our subsidiary or distributor site. 
For any inquiries, please contact your nearest subsidiary or distributor.
