Nikon d750 delay / snap delay – Exchange of stacks of photographs

I recently switched to a Nikon D750. I take photos half professionally, but I still learn a few things. An annoying problem that I can not solve with the new camera is that when I take the picture, I press the button halfway to autofocus, and when I press it down to break the picture, it takes about 1 second before the picture is taken. This is very embarrassing because I pull from my hands and not from a pod sort. I guess this is an easy setting, but my camera is not accompanied by a manual and I can not find the solution anywhere.
