Thank you for purchasing and using our products.
We have found that Live View Mode cannot be used on the EOS8000D (RebelT6s /760D) and EOS KissX8i (RebelT6i /750D) released on April 17th 2015 by Canon Inc. with some of SIGMA’s Canon mount interchangeable lenses. For those who own the lenses, we are going toprovide a firmware update free of charge.
[Phenomenon]
When the Live View Mode button on the camera body is pressed, the operation stops without displaying images on the rear LCD monitor.
