One disappointing note is at 7:30, regarding the Z6's setting a3.

  • "Choose 1 for quick, to make sure the camera tracks autofocus as fast as possible."

NOOO! The camera will always track as fast as possible. There is no point to the camera tracking slower than it can.

This setting actually tells the camera what to do when it loses the subject it is tracking (for example, as you are panning, a tree shows up between you and the subject. That's why it says "blocked shot AF response" and not "AF tracking speed."

Bingo, which is why your recommendation of having it set to 3 or higher all the time is not exactly correct. It all depends on the situation.

"[My] recommendation of having it set to 3 or higher all the time?"

Where did I write that?

Setting 1 tells the camera to immediately forget the subject and refocus on something new (like the tree).

This setting doesn't tell the camera what to focus on. Nothing to do with subject selection.

Read what I wrote again.

I didn't say it tells the camera what to focus on. I said it tells the camera to pick a new subject.

It tells the camera to wait before it moves from current subject to a new one, if you move the AF point to something else (it also makes the AF feel sluggish sometimes). This can work for you or against you, depending on the situation and expectations.

"From current subject to a new one?" But when I said something similar, you just argued: "This setting doesn't tell the camera what to focus on. Nothing to do with subject selection." Bold & underlined above.  Hmm...

What you just parroted back to me is what I said here and what I said originally, even in the previous linked post for the old firmware. You are engaging in a strawman argument.

Here is what I wrote on this subject:

  • Remember, this is AF-C, so this setting does not affect how quickly the focus keeps up with your subject. Instead, setting a3 tells the camera how quickly to forget your subject.
  • This setting actually tells the camera what to do when it loses the subject it is tracking (for example, as you are panning, a tree shows up between you and the subject. That's why it says "blocked shot AF response" and not "AF tracking speed."Setting 1 tells the camera to immediately forget the subject and refocus on something new (like the tree).Setting 5 tells the camera to wait a second or two to see if the original subject comes back into the frame (or gets unblocked) before deciding to pick a new subject.

And what you said was that you should always set a3 to 1 in all circumstances, that setting it to 1 increases the speed of initial AF acquisition, and that Nikon should have removed this from the menu. And also, that while a3 does not affect subject selection, a3 does affect subject selection.

But here: I've got my own a3 "blocked response" for you:

Enjoy, salty.
