[QUOTE="lokatz, post: 647239, member: 43924"] Hi Paul, in your post, you said 'Auto Fine tune', so let's clarify something first: a few newer Nikons (D7500, D850) indeed have an automatic function to fine tune AF, although I read repeatedly that it does not work all that well. Your D7200 does not have this feature. What your camera does have, in the Setup menu, is a MANUAL option to fine tune AF. Separately for each lens and, as mikew pointed out, also for each lens+teleconverter combination, you can adjust the focus point to move it a bit forth or back. This is done by setting a value between +20 and -20, where a + means the camera/lens combo will focus further away, correcting back focus, and a - means the camera/lens combo will focus nearer to the camera, correcting front focus. I don't use the software solution Don mentioned but do everything manually, which also works well.
