The Canon C400 has received it’s first firmware update today, and with it come some exciting auto focus improvements.

Auto focus now works in Slow and Fast mode up to 120fps. Also, the subject detection function will also work up to 120fps now. Using Auto Focus while in Slo-mo should be a much smoother process now.

This update also comes with the change of a default setting. The “Focus Ring Response” will now default to “Linked to Rotation Degree” instead of “Varies with Rotation Degree.” So, make sure you get used to the new setting, or change it back, depending on your preference before your next shoot.

Canon C400 Firmware 1.0.1.1 can be downloaded here.

Make sure you follow Canon’s recommendations when installing a new Firmware. The process for instillation can be found here.

The User Manual can be found here. An explanation on how the “Focus Ring Response” setting can be changed is located on page 88.
