For the primary time with an alpha digicam, all three eye AF modes can be found additionally for video taking pictures.

The autofocus is very customizable identical to with the current alpha cameras such because the a7S III and a1. What I discover actually attention-grabbing is the brand new Focus Map characteristic that visualizes the depth of area.

This may be very useful for guide focusing when you get used to it.
