Furthermore, we would like to announce that a new firmware update for SIGMA 24-70mm F2.8 DG OS HSM | Art for NIKON F mount improves on the phenomenon particular to the lens when it is used in combination with the Nikon “Z 7” or “Z 6” and their “Mount Adapter FTZ”.

For customers who own the SIGMA USB DOCK and applicable product listed below, please update the firmware via SIGMA Optimization Pro (before updating the firmware using the SIGMA USB DOCK, please ensure to update SIGMA Optimization Pro to Ver. 1.5.0 or later).

  • Applicable product: SIGMA 24-70mm F2.8 DG OS HSM | Art for NIKON F mount
  • Benefit of the update: When the lens is used in combination with the Nikon “Z 7” or “Z 6” and their “Mount Adapter FTZ”, it has corrected the phenomenon whereby it may occasionally show overexposure when narrowing down the aperture from F5.6 while shooting.
