Canon is offering owners of its Cinema EOS C100 the chance to add Dual Pixel AF to this video-centric camera. This will enable continuous autofocus during recording with all Canon EF lenses, and double one-shot AF speed with 104 fully-supported lenses. Interestingly the upgrade doesn’t involve a change of sensor, but instead enables a hitherto-unused hardware capability. However it will require the camera to be sent to a Canon service centre, and in the US will cost $ 500.
