Dual Pixel CMOS AF is a sensor-based, phase detection Auto Focus (AF) technology designed to provide smooth, high-performance focus tracking in movies and fast autofocus acquisition when shooting still photos in Live View mode.

It is a unique, Canon-developed technology, ideal for creating professional-looking pull-focus effects and keeping a subject moving towards the user in sharp focus while maintaining a blurred background – a defining characteristic of EOS Movies.

For more detailed information on this technology, please read the Dual Pixel CMOS AF story.

All Canon EF, EF-S, and EF-M lenses with autofocus can take advantage of Dual Pixel CMOS AF.

Certain discontinued lenses and lens and extender combinations cannot use Dual Pixel CMOS AF for high speed focus drive. In these cases Dual Pixel CMOS AF obtains the correct direction of focus before automatically switching to contrast detection. This is faster than contrast detect autofocus alone. Performance in Movie Servo AF mode, which uses slow speed drive, is not affected.

The lenses that do not support Dual Pixel CMOS AF high speed focus drive are listed below:
