Focusing

Face detection AF where it intelligently detects the faces in the frame and locks the focus automatically. In addition to the face detect AF, E-P7 has a more sophisticated feature called
Eye Tracking AF which detects and locks focus to the selected eye of the person in the frame accurately and tracks as the subject moves. Eye tracking AF of Olympus E-P7 is a perfect feature for shooting portraits and is especially useful when fast lenses are used and the depth of field is very narrow.
