Imaging recource: Sony mirrorless cameras will soon focus as fast as DSLRs if this patent becomes a reality

A recent patent publication from Sony shows off a new technology that could improve low-light autofocus performance in mirrorless cameras that use phase-detection or hybrid autofocus systems with the help of uniquely shaped microlenses atop individual pixels. Before we dive into the details of the patent, we need first to lay down an understanding of the two most utilized forms of autofocus and understand how they relate and can even work alongside one another.
