The Canon C100 is very popular with run-and-gun operators in the documentary world, and Canon recently announced an upgrade for the C100 that allows for continuous tracking autofocus with Canon's entire EF lineup. The upgrade will also increase the speed of the camera's existing one-shot autofocus by around two times and provide an AF lock, which will enable the user to change the image framing while keeping the desired focus point, a feature that is especially useful for run-and-gun filmmakers.

Many people have been asking for suggestions on scene files for the AF100, so I put together a couple that I think you might find useful. In the process of creating these files, I also discovered several ways to reduce sensor noise. Reducing the detail levels helped, but to my surprise, changing the Matrix settings to NORM2 seemed to make the biggest difference.
