Apparatus for an optical system optimized for PDAF depth sensing are disclosed herein. An example apparatus includes a phase detection auto focus (PDAF) sensor including a plurality of focus pixels and a plurality of micro lenses. The example apparatus also includes an optical system located above the PDAF sensor and configured to direct light to the micro lenses of the PDAF sensor. In some examples, the optical system includes a lens and an opaque element configured to block light through the lens except for at least one circular asymmetric subsection of the lens.
