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.
- 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.
