I have read through the past view years of comments on the topic and didn't see my question addressed.
The question of whether it is <<needed>> has been covered (with interesting comments about KR), but not whether it <<should be done>>. What's the difference? It might increase focus but create a pain in the a--. I write this because the D800 manual says, "AF tuning is not recommended in most situations and may interfere with normal focus; use only when required." So if Nikon doesn't recommend it, why? I assume people are not finding problems after AF fine-tuning, but I had to ask.
Whatever they recommend, a blurry picture is useless so what choice do you have?
and an old Tokina needed strips of shim under the mounting flange to get it to give a good auto focus picture !!!!
You will not create any problems only sharp pictures.
Spray....try your 24-35 at 35mm and f4 ..I often find the quality is so poor wide open on some lenses the band of sharpness is difficult to see
If I had such a lens, I would send it (along with the camera) back to nikon for a tune-up. In fact, you can give them all of your lenses and bodies and have them "zero out" everything.
If its a brand new lens check it again after a few hundred shots as they run in and it can change.
I have not sent one to Nikon because I cannot loose it for that long but if you cannot get it right Spraynpray is right send it back...keep the paperwork to boost its value when you sell it !!!!
This is a huge feature opportunity for upper-models. Some sort of AF feedback auto-adjust, maybe by comparing a hybrid phase-detect sensor to nearby contrast-detect sensors for each AF actuation, so that no aperture or distance can throw AF off. It seems that even the difference between f/1.4 and f/1.8 makes a huge additional demand on AF accuracy. So if you never move off of kit lenses, it's probably irrelevant.
At the other end of logic I don't even bother to focus my Samyang 14mm which is taped up at 10ft and F5.6 !!
Not trying to start an argument, just want information...How do you know Nikon is able to adjust a zoom lens for multiple focal lengths, and how do they accomplish that? It sounds pretty tricky. If it works well, I might try sending in my D7200 for a "tuneup" as it's still under warranty (although the only lens I have that requires a substantial micro adjustment is the 18-140mm kit lens that came with the camera, in its case +12, but I almost always use the better behaved 16-80mm in its place).
Generally I want the front windscreen or driver's helmet in focus, the front and rear can be a bit soft. This requires fine tuning, other wise the focus may be off 20cm or more even at a subject distance of 100 meters.
