So many buttons...
I now have 51 focal points....why?
I set up the back button but it still seems to search and I’m missing sharp pictures.
Do I need more practice, or lower to 21....help.

It would be good to know what you are shooting. Stills only require 1 focal point, action rarely more than 9. It is trial and error, practice, and more practice to learn what works best for each individual. More excuses to get out and take photos is not a bad thing.

I also have a D750 but only use 1 point especially when shooting people/animals because I want the eye in sharp focus. Then I decide how much depth of field for how much else I want in focus.

Just take pictures, and take time to get used to your new jewel. Multiple focal points are great for landscapes, single for wildlife and sports. Depends on what you like.

Back button focus does not make the camera focus any better or worse than the half press of the shutter button. They are only on/off switches. Be sure that if you activated the back button that you deactivated the shutter half press.

I have a D750 and use single point focus. 51 points means I can move that single point to 51 different positions.

Also try Group-area AF. The five focus points act as one focus point. You'll see four focus points in the viewfinder. The center focus point is hidden.

If everything fails just read the instructions manual.

I also have a new D750. I think they put a lot of focus points in there for situations like follow focus. I found how to get it down to just one focus point, which is what I always used on my D5100. (I hate it when a camera tries to guess what I want to focus on!)

You can change the 51 focus points simply enough by holding in the AF button on the left and moving the front selector wheel your focus point changes.
The advice above further shares with you how you may use these focus points.

I use a single center focus point and back button focus.

Try checking out Steve Perry's website about the back button focus settings. You may also find his book on the Nikon Focus system to be a valuable tool in understanding how the system works. I have found it to be of tremendous help in understanding things on my D7200.

Unlike holding the shutter release button half-way down, the back button focus will continue to focus as long as you press it. Press the back button to lock in the subject you want to focus on then release it. Then you can reframe your shot and the area you focused on will remain in focus. If you continue to hold the button down as you recompose your shot, it will refocus on another part of the scene making what you intended to focus on out of focus. The only time you would want to hold the button in is for action shots when you want the camera in follow focus mode.
