5 fancy phone camera autofocus technologies: from lasers to phase detection

5 current smartphone camera focusing technologies
Phase detection auto focus, lasers, infrared, focus pixels - a smorgasbord of smartphone camera focusing technologies has appeared lately, and each one promises to be faster and better than the others.

Check them out below.
