Canon EOS-1D X Firmware Update Article By Canon Digital Learning Center

EOS-1D X Firmware

Two weeks ago Canon released an important firmware update for the Canon EOS-1D X. This is a big update that brings improvements for auto-focus, exposure control, and more.

The Canon Digital Learning Center published a long and detailed article to explain all what you need to know about the firmware update. The highlights that come with the update:

  • Autofocus: improve low-light focus capability when tracking moving subjects in AI Servo AF
  • Autofocus: expanded range of Accel./Decel. Tracking settings toimprove AI Servo AF stability when focus-tracking subjects moving at a consistent speed.
  • AF point management: Orientation Linked AF adds a new option toregister only AF points rather than AF point plus area; Auto AF point selection in AI Servo can now start from the same AF point used last during Manual AF point selection.
  • Exposure control: Make Auto ISO even more viable (two important new changes), and a new option to maintain consistent manual exposure, even if aperture changes (such as if a tele extender is removed and shooting immediately begins after it’s removed)
  • Customization: New “back-button” options to instantly change AF characteristics on-the-fly
