EOS 5D Mark IV has another firmware update. Firmware version 1.0.3 addresses several different areas of the camera functions, and the one that is most interesting for me is the colour of images with flash exposure.

EOS 5D Mark IV firmware update v1.0.3

 

Canon says that firmware update v1.0.3 addresses the following items

  • Corrects a phenomenon in which the color of images varies depending on the metering mode selected during flash shooting.
  • Improves the reliability of communication when using the EF1.4X III or EF2X III extender.
  • Corrects the level display when the camera is held in the vertical orientation with the hand grip pointing downward.
  • Improves the reliability of communication via USB cable when using the Lens Data Registration function with EOS Utility 3.

EOS 5D Mark IV owners should download and install the updated firmware from Canon’s website, here’s a quick link to Canon’s download page.
