The F900EXR automatically switches between PhaseDetection AF and Contrast Detection AF depending on the subject and scene, guaranteeing superb ease-of-use and fast, accurate autofocus no matter what the setting or shooting conditions.
Photo Rumors hears the two shooters will switch to a newer, faster hybrid (both contrast and phasedetection) focusing system that also includes Sony NEX-style manual focus peaking, which provides a rough visual guide as to when a subject is as sharp as possible.
