I am not interested in how fast it focuses, but how well it locks onto the subject and stays with it. 500 PDAF points are useless if it can't stay on the same subject.

I just tried one at CP+. I enabled face detection, and locked focus on the face of someone walking towards me. I placed the face in the top left corner of the frame.

Then I slewed the camera as fast as I could from left to right, and immediately took a shot with the face in the top right corner of the frame.

I wasn't playing fair, but nonetheless the camera tracked the face across the frame, and took the shot (with the green rectangle still around the face which had turned into profile) the same instant I pressed the shutter. The face was in focus.

The AF system was clearly faster, and more surefooted than the NEX's and A7(r), and seems to be capable of tracking moving subjects. How it really performs in a wide variety of conditions remains to be seen, but it does look like it's the real deal.

A rose by any other name is still a chicken.

Hope I'm not too off topic here, but it seems that the FE 55 is a fast hybrid phase detection lens. (I posted this before.) So the 55 might be considered as the best narive E-mount lens for doing comparative testing with the A7, the A7r and now, the A6000 bodies.

"" the term "advanced electronic-optical hybridization" leaps out at me from this Sony review of the Zeiss Sonnar T* FE 55mm F1.8 ZA lens. This seems to be the Sony term for "Fast-Hybrid AF."


Also seen via this page, there's this about 2X Clear Image zoom which is attainable with this new lens: "Clear Image Zoom makes this prime lens into a video zoom lens; e. g., Clear Image Zoom 2X through the Sony FE 55 mm F/1.8-F/22 Carl Zeiss prime lens, takes it up to 110 mm telephoto. Thereby, this lens can take portraits with spectacular F/1.8 bokeh or close ups with exquisitely detailed F/22 razor-sharp compositions"""
