Earlier this year Canon announced they would be adding One-shot autofocus to the C300 EF mount version via firmware. Today they delivered on their promise with firmware version 220.127.116.11.00 and added a raft of extra functions as well. The AF is similar to the original C100, but not the same as the speedier Dual Pixel AF CMOS that you get with the paid C100 upgrade that will be available soon. Continuous AF is possible when using one of the newer STM lenses.
Other improvements for the C300 EF and PL versions include the ability to move the magnified focus area around the LCD screen when checking focus. There is also the ability to record 1440×1080/35Mbps in camera for users that are working for clients who need this lower resolution. The camera gets a new 80,000 ISO setting which improves on available options for a camera that was already one of the best in low light. A wide DR gamma option has also been added.
There is also a new version 1.3.2 of Canon’s XF Utility that can correctly show metadata of clips shot in the new Wide DR mode.
Here’s the info from Canon:
Firmware Version 18.104.22.168.00 incorporates the following additional functions and modifications:
