Sigma issued a service notice (from Sigma Japan) regarding a Live View issue withthe Canon EOS 5DS and EOS 5DS R camera bodies and some Sigma zoom lenses.

When the Live View Mode button on the camera body is pressed, the operation stops without displaying images on the rear LCD monitor.

More Information

  • If your lens was updated to be compatible with the EOS 760D / 750D, then it will also work with the 5DS / 5DS R. Otherwise you will have to send it to Sigma for a free firmware update.
  • Lenses shipped after May 11, 2015, already have the new firmware and will work in Live View with any current Canon DSLR.
  • Users of the 120-300mm f/2.8 DG OS HSM Sports – the only Global Vision lens to be affected by this issue, see list below – can do this at home using the USB Dock and Sigma Optimization Pro.
