CPN has posted an article explaining the dual pixel technology upgrade for the Cinema EOS C100 camera.
How does dual pixel CMOS AF work?
Dual Pixel CMOS AF is a sensor-based, phase-detection autofocus (AF) technology that’s designed to provide smooth, high-performance continuous focus in movies. It is a unique, Canon-developed technology, ideal for fast and accurate autofocus, helping filmmakers to create stunning footage which maximises the creative options offered by fast lenses and shallow depth-of-field.
The EOS C100 camera with Dual Pixel CMOS AF technology features a CMOS sensor that consists of an array of pixels that each feature two separate photodiodes. By continuously comparing their outputs during AF Mode, phase-difference autofocus helps to ensure non-blurred images and smooth focus transitions even when the subjects and/or camera are moving. The new feature places a high priority on maintaining sharp focus while, providing a natural, smooth autofocus movement with selected Canon EF lenses that offer even smoother and quieter operation.
After this modification, the EOS C100 camera's Continuous AF function active area represents 20% of the image vertically and 25% horizontally, yielding a very large, centrally located autofocus zone. The AF Lock mode allows you to set focus and hold it, allowing you to change framing while maintaining the original point of focus.
