Caveat -- I do not have the a7rIV, I'm trying to help someone elsewhere.

Over in a FB group for Sony, a user reports that when using the timer (e.g. for a 10sec delay) the AF appears to lock at time of shutter-depress. Then if he's doing a selfie (e.g. against a background) the bg is crisp but the subject is blurred. AF-C is explicitly greyed-out and unavailable.

Is this correct?

Is there any way to explicitly direct the camera to AF at the time the shot is taken, instead of when the timer is released?

That's how every Sony camera I've ever encountered does it.

The best way is to use a wireless remote for that rather than the camera's timer.

Another approach is to use Smile Shutter if the camera has it. That keeps taking shots as long as the subject can keep smiling - essentially it's AF-C mode with focus and shutter release triggered by any detected smile.

As mentioned above this isn't specific to A7RIV all my other Sony camera have done the same.
