Nikon has several sensors that they call dynamic- 3D, D25, D9, auto & D51 (D3) , Grp4 (810). Then there is the good ole single sensor. These are obtained by pressing the center button on the AF switch (left side lens flange bottom)While pressing turn the top wheel and you'll page thru all of them.

Its a combination of high shutter speed and aperture and concentration.

Why do you say that?

What camera is it?

The attached shots are shot using D3, D810, D600. None of the cameras have eye focus. I use a variety of dynamic sensors that fit each shooting scenario.

I shot this hawk last sunday coming of the Ottawa National Wildlife Refuge on Veller Rd. Iused a Nikon D600 and a 200-500 lens.

Go look at my version of this shot on page 1.

The hummer in the above is too dark.

Here is how I processed the file. I surrounded the bird first with marching ants and used highlight/shadow slider. I left the marching ants on while I used Topaz Denoise AI to sharpen. Then I unselected the marching ants and then I surrounded the flower with the marching ants and used the highlight/shadow slider, brightness and contrast sliders. I also removed a couple of background items.

I would first use the highlight/shadow slider. Its too dark.

I know that setting my cameras to #9 sharpening is working correctly. In 2015 I'm using my D600 and my Sigma 800mmF:5.6 AF and I shot a Cape May at minimum focus and I printed it at 24x48 and it lost no detail, did not go into pixels. In 2019 I"m shooting the eagle nest at Magee Marsh and I'm using D810 and my 600mm F:4G VR and I got the eagle coming off the nest and eye sharpness is incredible. A friend was shooting behind me with a D500 and 600mmF:4E VR. He looked at my shot and went out and got a D850. I've seen this work in too many cameras. In fact I began using it when I had my D1x. I shot some butterflys and when I downloaded the shots they were all soft. I took the camera back to my money back and a counter guy showed me the sharpening trick. I've since on all my cameras. I tryed fine tuning my 800mm. I had to be 132 ft away from the target. You cannot even see the 2 red ball to line up correctly at 132 feet. Also the OP might be S instead of C for focus. This will make a big difference in locking focus.

Nikon has told me that it applies it to each raw file and jpg file. Steve Perry and E. J. Piker with Naturescapes.net, both have confirmed it to me and I have personally have seen it work with others in the field that I've helped

You can go into your shooting menu and press at 3 oclock to vivid and press at 3 oclock and set sharpening to #9. I have 6 Nikon cameras and 13 lens and all my cameras are set to sharpening and #9. I have no problems maintaining sharp images. I've written a PDF on this subject. Drop me a line and I'll send it to you.

you should go into "picture control" right push on the control wheel(3PM) and set one one of the choices and push the wheel at 3pm again and move sharpening over to number 9. I know you folks are going to yell about this but I have seen it work too many times. You should write me and I'll send a PDF to you that covers this and a host of picture possibilities. I have 6 DSLR's and 12 lens and nothing is calibrated and I get tack sharp images with 200-500/D600/D810. You can reach me at Larrys@bex.net
