Getting eyes sharp quickly, moving model, camera w/o eye detection

What techniques and settings help you get eyes in focus fast while shooting a model who is moving moderately?  Assume a camera without eye detection (Nikon D850)?

Thanks...

I would try AF-C Group AF with the cluster on the head/face.  Also if the whole body is within the depth of field you could also use AF-C D9 as it would be difficult to track head/face with AF-C single point depending on how fast they are moving.  Unless the depth of field is razor thin this should be a relatively easy task in either mode.

Try using back button focus with continuous servo AF. That's what I did with my D750 before I started using a camera with eye AF.

Klaus. In between the strobes is the studio dark? If so how does that affect how you work with the model? Or do you keep a modeling light on? Thank you.

Re: Getting eyes sharp quickly, moving model, camera w/o eye detection

As you write, strobes have model lights. They are lit as long as we shoot (I toggle model lights from the on-camera controller), but while the strobe recharges they are off. In my case that's about 1/4 second.

Either the room lights are on, or I shoot in the living room with window light, so it's never completely dark in the studio. I have exposure simulation turned off, so the viewfinder never goes dark.

The ambient must not affect exposure. If I'm in doubt, I turn off the controller and take a shot by the ambient light only. If the picture is very close to black, everything is OK.

Thank you, Klaus. Very instructive.

Glad to hear that. The D850 has face detection, have you used face detection? I gather from your post that is not needed. I am just talking about the model moving around in different positions, not a lot of movement compared to sports.

Were you using a single point?

Yes, single point.

I typically shoot a little wider than Klaus; generally f8. It definitely helps. And, like Klaus, I shoot with a modeling light on to help the camera's focusing system. 
I almost always have my models constantly drift and move, rarely static. And having it set up that way worked pretty well. Not as convenient at the tracking auto AF on my current camera, but certainly good enough.
