For the first time on a Canon traditional camcorder, the XF405/XF400 features Canon’s innovative Dual Pixel CMOS AF focusing, ensuring smooth focus transitions and pin sharp accuracy.
Dual Pixel CMOS AF is a sensor-based, phase detection Auto Focus (AF) technology designed to provide smooth, high-performance focus tracking and fast autofocus acquisition. It is a unique, Canon-developed technology, that uses two photo diodes per pixel for autofocus and combines them for recording video.
This allows accurate focus to be maintained, even with moving subjects, which is vital for 4K capture and makes single operator shooting more efficient.
Using Dual Pixel CMOS AF technology to confirm manual focus, the GUI first seen on Cinema EOS cameras indicates which way the lens focus ring needs to be turned to achieve accurate focus.
