1) Fastest auto-focus of any camera.
2) Register subjects=in a group of people, lock onto and focus on one person. Even if that person leaves the frame and returns, the camera will lock on them.
3) Set shutter to fire when someone smiles in a portrait shot. Amount of smile is programmable, too.
4) Sony apps allow you to remotely shoot from smart phone. I assume other cameras have this.
5) Focus can lock on eyes, not nose.
6) Shoots at up to 11 exposures/sec.
7) Use other brands of lenses with adapter.
8) Intelligent auto mode that senses the subject (person, landscape, etc). Even automatically differentiates between babies and adults to render skin tones.
