First of all, lens calibration is a dangerous road. I own four Nikon camera's, 2 D500's, a D5 and a D850. I shoot wildlife photography. I have been using the Nikon 200-500 5.6 on all four camera's WITHOUT having to do any lens calibrations and I get perfectly sharp images with all four camera's without lens calibration. On a zoom, once you calibrate for a certain distance, you are only good for that distance and zoom level, if you change zoom level or distance then your off your set calibration. Same with a prime lens, once you calibrate for a certain distance, you are only good for that distance, change distances, your off your calibration again.
Don't take my word for this, the Nikon boys at Melville New York say the same thing. I have over 20 Nikon AF lenses and have not had to calibrate one to get sharp eye focus on any bird I have shot over the past three years.
The D5, D850, and D500 all share the same focusing system. Nikon has put a separate focusing engine into these camera's to assure true, accurate focusing.
To sum up, you can calibrate for a certain distance (one distance only). BUT, once you change that distance, your calibration is no longer accurate. Again, don't take anyone's word here (they will tell you differently) relay on the boys at Nikon to set you straight before you start playing with your expensive equipment and going down a dangerous road.
