A062 & A067 Firmware Update: Important Sony E Fix

The A062 A067 firmware update Sony E service notice addresses a focus-position issue affecting two TAMRON lenses for Sony E-mount cameras. The affected lenses are the 20-40mm F/2.8 Di III VXD (Model A062) and 50-400mm F/4.5-6.3 Di III VC VXD (Model A067).

The original issue occurred when the camera’s AF Assist function was set to Off. Under this condition, turning the lens focus ring could cause the focus position to shift unexpectedly. TAMRON released firmware to correct the issue and recommended that affected users update their lenses.

Both lenses have since received additional firmware updates. As of the latest TAMRON firmware information, the Sony E-mount A062 is on Ver. 4, while the Sony E-mount A067 is on Ver. 5. Both versions add compatibility with TAMRON Lens Utility Ver. 5.0 and TAMRON Lens Utility Mobile Ver. 5.0.

A062 A067 Firmware Update Sony E: What Was Fixed?

The original firmware update addressed a specific focus-position problem involving the camera’s AF Assist setting.

When AF Assist was set to Off and the focus ring was turned, the focus position could shift. This behavior was identified on both the A062 and A067 Sony E-mount lenses.

TAMRON subsequently released firmware to correct the phenomenon. Users can update the affected lenses themselves using TAMRON Lens Utility, or, where applicable, have the lens updated through TAMRON service support.

Original Focus Position Issue

The original service notice was issued after TAMRON identified a specific phenomenon affecting certain Sony E-mount lenses.

When the camera’s AF Assist function was turned Off, manually turning the focus ring could cause the focus position to move.

The affected models were:

• 20-40mm F/2.8 Di III VXD (A062)

• 50-400mm F/4.5-6.3 Di III VC VXD (A067)

• 150-500mm F/5-6.7 Di III VC VXD (A057)

This article focuses on the A062 and A067 service notice.

Why Firmware Updates Matter

Lens firmware controls communication and functions between the lens and compatible camera body.

As camera systems evolve, firmware updates can improve compatibility, autofocus performance and support for new camera or software functions.

For the A062 and A067, the original update addressed the focus-position issue. Later firmware versions have continued to add compatibility with newer TAMRON software.

Keeping the lens firmware current therefore helps ensure that supported features remain available when using newer versions of cameras and TAMRON Lens Utility.

Compatibility with TAMRON Lens Utility

Both lenses now support newer versions of TAMRON Lens Utility.

The A062 reached Ver. 4 and the A067 reached Ver. 5 on February 19, 2026. Both firmware versions added compatibility with TAMRON Lens Utility Ver. 5.0 and TAMRON Lens Utility Mobile Ver. 5.0.

TAMRON Lens Utility allows users to configure supported lens functions through a compatible computer.

The software can also be used to perform firmware updates on compatible TAMRON lenses. TAMRON’s firmware instructions explain that applicable lenses can be connected to a computer and updated through TAMRON Lens Utility.

A062 and A067 Sony E-Mount Compatibility

This service notice applies to the Sony E-mount versions of both lenses.

The A067 also uses TAMRON’s VXD autofocus system and VC image stabilization.

Firmware Ver. 4 previously improved AF performance during zooming and added high-speed continuous shooting support with the Sony α9 III. Ver. 5 subsequently added compatibility with TAMRON Lens Utility Ver. 5.0 and TAMRON Lens Utility Mobile Ver. 5.0.
