Canon C100 Firmware Update

Canon C100 Firmware Update

Canon EOS C100

Canon have released firmware update for the EOS C100, which now features continuous focus tracking of moving subjects and XLR modification.

Our friends over at Planet5D picked up on this first, with one of their moderators commenting on the functionality of the feature:

“OK I downloaded it and installed it on the C100 just before the camera left our building and did some very quick tests using the 18-135mm STM lens. The AF in Focus Lock mode was very fast and smooth. Much better than before.

AF in Continuous mode (which is accessible as a setting in the camera menu) is fully continuous which means it keeps focusing without any interaction.

The One Shot (focus lock) AF mode still requires you to push the Focus button on the front of the camera body.

In my initial test, I was very impressed with the speed and smoothness of the Continuous Focusing. It was very good in very low light, and would probably be even better in good light. It seemed to track a moving person diagonally very well, which is not easy for most contrast detection systems.”

Here is the press release from Canon:

The XLR modification sounds like a tweak more than a new feature, and whilst the continuos focussing sounds positive in regards to functionality, it’s use in the professional world is likely to be limited. Will you have a use for this feature? What did you hope to see from a C100 firmware update?
