Implementation of Subject Detection A1 M2, A7RV A7CR A7CM2 in video...

[Interceptor121]

As it happens to my A7CM2

https://helpguide.sony.net/ilc/2440/v1/en/contents/211h_about_eye_af.html

All Sony newer camera switch to full screen when shooting video with subject detection

• The camera focuses on the recognized subject's eye, head, or body or the entirety of the subject anywhere on the screen, regardless of the setting for [
  
  
  
  Focus Area]

It also seems that switching subject is only allowed for humans and I am not clear if this is even possible for Video

ILCE-1M2 | Help Guide | Selecting a person to track (Select Face to Track)

Which leads me to the question if I have two potential subject in the frame: i.e. two deer fighting, a flock of birds, multiple cats I have no control on what the camera is choosing to focus in video mode

When it comes to tracking

ILCE-1M2 | Help Guide | Tracking subject (Tracking function)

The functionality is essentially unchanged from the original A1 A7 IV all the way to newer models in movie mode you need to touch the display to start tracking what you want

If I compare how my Panasonic GH7 operates this camera tracking is essentially not useable however using standard subject detection I am not forced to use the whole screen, using a small explandable area I can choose where to focus in the frame in both photo and video and this ensures I am staying on the subject I choose I can also move the target area while shooting with ths joystick

Ideally a combination of both would be cool where you can choose the subject and then start tracking and still move it like it happens in still mode

After all this marketing hype about improved Autofocus in the newer models I am not really so impressed it seems pretty basic and really only worthwhile when you have a clear single subject in the frame, but that scenario would work anyway regardless of sophisticated subject detection except the camera would (maybe) focus on the eyes

I think I didnt make myself clear here and also rereading it I think i got it partially wrong

Option 1 without function key will focus wherever the focus area is the second with function key will go for the whole screen

none of them in case of multiple subjects allow you to choose which one if multiple subjects are detected is your subject

however if you set the first to expand spot I should end in the same point of my Panasonic gh7 with the a7cm2
