Sigma Releases Lens Firmware Updates to Address Nikon D500 Underexposure Issue

Sigma has firmware updates available for the following lenses:

  • Sigma 35mm f/1.4 DG HSM Art
  • Sigma 17-70mm f/2.8-4 DC Macro OS HSM Contemporary
  • Sigma 18-300mm f/3.5-6.3 DC Macro OS HSM Contemporary
  • SIGMA 120-300mm f/2.8 DG OS HSM Sports

All three firmware updates resolve an underexposure issue when the lens is used with a Nikon D500. The 120-300mm f/2.8 DG OS HSM Sports firmware update is only required if using a TC-1401 or TC-2001 teleconverter with the lens.
Sigma Global Vision lenses (like the ones above) can be updated using Sigma USB Dock. Before updating, be sure to download and install the latest version of Sigma Optimization Pro.
If you do not own a USB Dock, you can send your lens to a Sigma Service Center and have its firmware updated free of charge. However, considering the cost of shipping a lens insured and the universal nature of the dock, simply buying the USB Dock seems to be the most practical way to update your lens’ firmware.
