I've done two things. I have never tuned a lens, and I have spent a lifetime tuning my techniques.

On another note, go Mirrorless and you won't have that problem.
"One of the main advantages of mirrorless cameras is that the AF is the imaging sensor itself, meaning there's no disparancy between two separate sensors, hence, focus is always 100% accurate. No AFMA needed", DP Review.

Without knowing the brand and model of camera and lenses, it's pretty hard to give you helpful advice.

EDIT: Okay, I see it now...

"Nikon D7100. In the menu under the fine tuning there is a "List Saved Values" and under that I found multiple lenses listed and the adjustments. Assumed there were lenses from the previous owner. When I saw this, it made me wonder if my lenses needed to be adjusted. I have the kit lens that came with the D5100, A Nikon 55-200 4-5.6, a Sigma 70-300 4-5.6 and a Tamron 17-50 2.8.

I'll leave it to others to recommend some methods to test the accuracy and, if necessary, make adjustments. I use Canon gear and am liable to give misinformation.

Honestly, I think there are better ways of using your time. If something is obviously out of focus, it's either the camera, the lens or you. I'll buy that some aftermarket lenses may be off, and some OEM lenses were dropped by the UPS man. Those need to be returned or exchanged.The kind of changes seen from this process are mostly imperceptible.

Ok, Ok, folks that do this will respond that their work produced dramatic results. I'm inclined to think they have too much time on their hands.

Most of the time you will find that, MAYBE, fast lenses with wide apertures do require from time to time, fine tuning for a particular distance. On Nikon you can only fine tune for one distance at a time.
Many times it turns out to be owner error and not lens error.
Nikon cautions against it, as do many user guide books about camera's. Nikon would rather you send your lens and camera into them for fine tuning.
When YOU fine turn a lens many things can go wrong and you end up worse than before you started.
A lens with smaller wide apertures and zoom lenses are sometimes best left alone.
I suggest you shoot the living daylights out of your lens and see for yourself if anything is needed, you may well find out nothing is really wrong with the lens.
Remember, proper handling and proper settings on your camera can go a long way in getting good results.

If you have never TESTED your focus then I can see why you have never tuned it in ! Ignorance is bliss ! Most of us who spend big bucks want to KNOW we are getting the best the lens has to offer.

I will admit that I am a photographer, who takes pictures. I suspect you are a lens tester.

I can't believe that of all the people that do this more than 5 to 10 percent will get better results, or a better result that can be seen without viewing at 100%. Frankly, I don't care if my camera is performing at 100%. I care if my camera produces the results I want. I know very few people that need this effort to produce the best they can. And to be honest, I'll bet I can count the ones on this list in that category, and I'll bet most of them don't waste time on these sisyphean tasks.
