Tamron 28-75mm f/2.8 Di III VXD G2 Firmware 3 (Nikon Z)

Tamron 28-75mm f/2.8 Di III VXD G2 Firmware 3 (Nikon Z) is the software update Tamron published on 12 November 2026 for the 28-75mm f/2.8 Di III VXD G2 lens, model A063, in Nikon Z mount. It downloads from the manufacturer's official firmware page and installs through TAMRON Lens Utility.

Version 3 adds compatibility with TAMRON Lens Utility 5.0 and TAMRON Lens Utility Mobile 5.0. With that software in place, the lens gains access to the new TAMRON-LINK features. The release arrives after Tamron postponed it from 10 June 2026, and replaces version 2, which had added support for the 3.0 tools.

Installation is not a matter of copying a file to a card: the lens connects to TAMRON Lens Utility, which handles the transfer. Tamron warns that a lens updated to the latest version cannot be rolled back to an older one, so it is better to update with time to spare before a job than in the middle of a session.

In use, the Tamron 28-75mm f/2.8 Di III VXD G2 Firmware 3 (Nikon Z) changes neither the optics nor the autofocus: what changes is access to the tools. Anyone who adjusts focus ring behaviour, stores custom settings or uses TAMRON-LINK on a Nikon Z body needs this version for the app to recognise the lens. On a standard zoom used every day, keeping firmware current avoids the app stalling on an unsupported version.
