Lower end Nikon with best focus?

I got a D90 last year and like it but still I am getting too many blurry shots. I am using a brand new 50mm AF-S lens.

I am considering getting a better Nikon if that would help. What lower end models have a better focusing system that would make it worth while to get?

I do newbie models and they as newbies have a hard time being still as they are nervous until they get used to the camera.

- Dean Lautermilch Photography are sample shots.

I would spent the money for a lower end Nikon even used that could better keep up with the movement than my D90 can.

Dean, unfortunately, linking us to your website for sample images does not provide for EXIF data to see what's going on with the shots. I'm also assuming you wouldn't have problem shots as part of your portfolio.

If you share a problematic image that you've captured with your D90 and current 50mm, we can take a look at where the problem comes from.

OK, here are two example RAW files
Four shots - https://www.dropbox.com/sh/xbcpl7hnnefsxwj/AABrhHdpxsZAiAOB6qfpmwY1a?dl=0

The first and third one is in focus. the second and fourth were taken a second or two after the preceeding shot.
All times I was focused on the eyes.

A few things:

First, you're shooting aperture priority mode, but have exposure compensation turned down three stops. Just confirming you've intentionally trying to under expose your shots in camera. (Usually that's an accident)

Second, you're shooting at f/2.8. While shooting stopped down some is sharper for your f/1.8 lens, that's still a pretty narrow depth of field.

Finally, here are some screen shots that show where the camera focused. This, along with the depth of field, is probably why two of the shots are not in focus.

The first image, no problem as you mentioned. Focus was on the eyes.

Screen Shot 2018-07-06 at 11.32.26 AM.jpg

Second shot, the focus drifted to the branches behind your subject. Because of the shallow depth of field, the face is now slightly out of focus.
Screen Shot 2018-07-06 at 11.32.43 AM.jpg

Again, good focus on the eyes, the face is in focus.

Screen Shot 2018-07-06 at 11.32.58 AM.jpg

I just screen shot around the subject's face, but on this image the camera did not report achieving focus.

What AF mode do you typically shoot in? Single point or multi-point? AF-S (single serve) or AF-C (continuous focus)?

its on AF-C

If he has it set for AF-C, then the next thing to determine is if it's set for Focus Priority or Release Priority. Focus Priority won't allow the shutter to fire if the image isn't in focus. Release Priority allows the shutter to take the pic even if focus isn't achieved. Seeing what RocketCowboy posted where the last shot in his comment didn't achieve focus at all, then my guess is the body is set to Release Priority.

If you are using my previous D90, I only ever used it in AF-S and never had any problem with the focus locking. Check out what RocketCowboy said. Perhaps change Release Priority to Focus Priority and see if that helps. The D90 is a great body. No doubt there is still a lot of life left in yours, but please check the AF-C settings.

Also, shooting at f2.8 will not help either as the depth of field is so shallow it is possible (when shooting close up portraits) to have just the eye in focus and the tip of the nose out of focus.
Stopping down to f4 will give greater depth of field and add the fact that the lens will likely be sharper at this aperture than at f2.8.

but turn up the light, ev -3 is too dim
but it will stop the action at 1/4000

Since he's shooting in aperture priority mode, my guess is the -3 ev is to keep the shutter speed up while shooting fairly wide open. It looks like auto ISO is also in use, so aperture is being controlled for creative effect while the camera decides between shutter speed and ISO to correct the exposure.

No doubt you are correct. Pretty tricky exposure management, highly sophisticated shooting.
Would have never occured to me to do it that way.

But the D90 does hit its limit at 200 and 1/4000. Maybe some shade or an ND filter is in order if -3ev is important.
