Canonrumors.com found a Canon patent for quad-pixel autofocus... what does this mean?! Tony Northrup digs into the weaknesses of Canon's dual-pixel autofocus by demonstrating how horizontal phase detect AF sensors it can fail with simple horizontal subjects. He then demonstrates how vertical and diagonal PDAF sensors can solve that problem - such as those in the quad-pixel autofocus patent.
