A6400 Animal Eye-AF

Sony has recently introduced the long awaited Firmware 2.0 upgrade for the A6400 providing Full Time Animal Eye-AF to that camera. It works great! Do I absolutely need it when photographing dogs, not really. I have been doing dog portraits all my life starting with Manual Focus Rangefinder cameras. But, the Full Time Animal-AF really makes things easier...
ILCE-6400    FE 70-200mm F4 G OSS    71mm    f/4.0    1/250s    ISO 250

A6400 firmware 2.0... 70-200mm f/4.0 G OSS lens wide open at 71mm

Normally a camera's AF will try to focus on a dog's nose since that is closest to the camera and you need to tell the camera to focus on the eyes. Full Time Animal-AF eliminates that one step and instructs the camera to focus on the eyes first off.

IMO, it works great!
