A few problems have also been fixed in this update. First, it resolves an issue in which a zebra pattern would appear on the HDMI output if the camera's screen was turned off during HDMI connection. The firmware update also addresses an issue where adequate picture stabilization effects may not be achieved right once after the camera is turned on. Canon has increased stabilization when using two lenses: the RF400mm f/2.8 L IS USM and the RF600mm f/4 L IS USM
EOS 1DX Mark III (Canon)
Canon Log 3 is now available in the Log settings for the 1DX Mark III, thanks to firmware 1.5.0. According to Canon future versions of the Cinema Raw Development in the Digital Photo Professional software will include support for RAW films recorded with Canon Log 3 and RAW (Light), as well as support for the processing of RAW movies produced with Canon Log 3 using the Viewing LUT.
With the exception of RAW and RAW (Light), which cannot be recorded on both cards at the same time, the update adds the ability to simultaneously record videos on both memory cards. Support has now been added for VPG 400 (Video Performance Guarantee Profile), a standard based on the CFexpress 2.0 specification.
Finally, this update corrects an issue in which shooting settings for still photographs are sometimes preserved while switching to video mode.
