Canon Firmware Update for EOS C70

Canon’s first RF-mount cinema camera is getting an update that adds functionality and improves performance.

HDMI View Assist

Adds the View Assist feature, which allows for a WideDR/BT.709 LUT to be displayed over HDMI when shooting in a Canon Log gamma.

Improved AF Feature

This update adds a “Whole area” option to the AF Frame size, increasing the AF area to 80% of the frame. When “Whole Area” is selected, the AF switches to “Tracking” by a single touch operation and switches to “Face Detection” when a face is touched.

When Using the EF-EOS R 0.71x adapter, the Possible AF Range Frame is now only momentarily displayed when selecting the AF Frame position.

Expanded EF Lens Support When Using the EF-EOS R 0.71x Adapter

adds the following lenses, fully compatible with DPAF, optical corrections, and metadata transmission:

  • EF16-35mm F2.8L II USM
  • EF16-35mm F4L IS USM
  • EF24-105mm F4L IS USM
  • EF70-200mm F2.8L IS II USM
  • EF70-200mm F2.8L IS III USM
  • EF70-200mm F4L IS USM
  • EF70-200mm F4L IS II USM

Firmware for the C70 is expected to be available for download on June 30, 2021.
