Canon have announced an optional upgrade for the EOS C100 which will support  their Dual Pixel CMOS AF autofocus technology, enabling continuous autofocusing with Canon's entire EF lens range. This optional upgrade is expected to be available in Spring 2014 for a cost of £339 + vat  and will require you to send your  C100  body to a Canon service centre.

The Dual Pixel CMOS AF technology was first used in the EOS 70D DSLR camera launched in August 2013. The new AF technology helps facilitate greater shooting efficiency across a variety of shooting situations. You should end up with a smoother, more natural autofocus that can be particularly useful for sports, event and wildlife video shooting.

Canon's Dual Pixel CMOS AF makes use of the Company's proprietary CMOS sensor technology with a new structure that both captures light and performs phase-difference detection autofocus. Also, the inclusion of an AF Lock function contributes to expanded shooting flexibility through focus preset, which allows users to set a desired focus distance in advance, and the ability to alter the photographing range or composition after establishing focus.
