The C300 Auto Focus Upgrade is scheduled to be available late May 2014 for a fee of $500 directly through Canon.
Originally introduced in the Canon EOS 70D Digital SLR camera, Canon Dual Pixel CMOS AF technology is designed to provide continuous autofocus when shooting in single operator, or run-and-gun set-ups like documentaries, weddings, events, or electronic news gathering (ENG). When used in combination with an STM lens, this technology allows for the capture of high quality video without the interruption of noise by the focusing motor.
Dual Pixel CMOS AF is an innovative image-plane phase-detection AF technology that employs a CMOS sensor on which all of the effective pixels are able to perform both imaging and phase-detection AF simultaneously. Although camera operators can still focus manually, this new optional feature upgrade can enable smooth continuous AF with phase detection, a particularly useful feature when shooting with a small crew or single-operator run-and-gun filming and cinéma vérité style shoots.
The optional Dual Pixel CMOS AF feature upgrade for the EOS C300 Cinema camera supports continuous AF with all compatible Canon EF series lenses when shooting subjects positioned in the center of the imaging area. The technology involves complementary use of a contrast signal to achieve advanced autofocus stability that helps reduce the occurrence of loss of focus on a subject. Also included is an AF Lock which allows users to lock a focus point once AF is achieved and recompose the shot. Canon Dual Pixel CMOS AF also nearly doubles the speed of the EOS C300 Cinema camera’s One-Shot AF function, which enables a DP to focus on a subject located at the center of the screen with the push of a button, a feature that is currently supported on 104 Canon EF lens models.
The Dual Pixel CMOS AF feature upgrade for the EOS C300 Cinema camera will be made available to users through an authorized Canon service center. For more information please visit the Canon U.S.A. website at http://pro.usa.canon.com/EOSC300FeatureUpgrade.
