New 5D Mark IV Firmware – V1.03
Canon have released firmware update V1.03 for the 5D Mark IV, you can download it HERE. Below is a list of improvements, and whilst most firmware updates typically contain seeming outlier cases, this one includes a fix for any usage with the 1.4x III and 2x III extenders. A high proportion of 5D users will probably use one of these at some point, so I’d rank this update a little higher in importance than most that I usually post about.
Firmware Version 1.0.3 incorporates the following fixes and improvements:
- 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.
