Auto Af Fine Tune D800
Here’s a 12-minute video in which photographer Steve Perry shows how to use the relatively new “Auto AF Fine Tune” feature from Nikon.
If your camera is back or forward focusing, then it’s likely you need to fine tune the autofocus. Cmake and dev c++. Often this would involve buying a commercial kit, or doing a bit of guess work, and in more extreme cases even sending your DSLR back to Nikon itself.
However, that is set to change with the Auto AF Fine Tune feature that is present on cameras like the Nikon D5, D500, D7500, and most likely any future mid-to-pro level cameras. (Here’s looking at you, D850.)
“The typical way Auto AF Fine Tune is performed by most users leaves a LOT of room for errors, inconsistency, and can even make things worse,” Perry tells PetaPixel. “In this video, I outline what AF Fine Tune is, proper setup, and a technique that gets me VERY similar results to what I see with commercial products.”
By using a target that is full of information for the autofocus system to lock onto, as well as ensuring it is properly lit, you can properly fine tune your camera’s focus for different lenses.
Unfortunately, you can only set a single fine tune preference for each lens. So for zoom lenses that have a varying AF compensation value across their range, you’ll need to compromise and go for a mid-point.

Using the AF fine-tune command here in the Setup menu, I can refine my camera's understandingof a particular lens's optical characteristics.In other words, I can make it focus better with a very specific lens.Now in the real world, you really only going to notice the difference if you're workingwith a lens that can open to a very, very wide aperture, so a 2.8 lens or a 1.8,. The D850 can fine-tune autofocus automatically. The results can be used with all lenses of the same type. Use only as required. AF fine-tuning should be performed at the focus distance at which the lens is normally used; finetuning performed at short focus distances may be less effective with distant subjects and vice versa.
