Here's a much easier way to figure a reasonable target distance if you're used to working in feet rather than meters, using 30x the focal length as a general guide. For a 50mm lens, that's 50mm x 30 = 1500mm which converts to 4.9 feet-call it 5 feet for our purposes. So just take the focal length of the lens, move the decimal point one to the left, and label it feet. For a 24mm lens, 2.4 ft. 105mm lens, 10.5 ft. Plenty close enough to get into the sweet spot of that 25x-50x range.

[@mikeanntroutman6463]

Do we need to multiply by the crop factor for aps-c systems?

[@802brundogsaint]

6 years later this is still helping people ! Thank you!

[@allabouthim03]

I have a D500 and the Sigma 70-200mm Sport. I already knew the lens was back focusing really bad, it needed somewhere between neg 15-20 to get sharp. Great Video but I fight for about an hour to get it to work. THIS IS WHAT I FOUND. I kept getting a message about "Focal Lenght" when I pressed the 2 buttons. I was using Steve's formal as to how far away I needed to be from the focusing print out. So I set up at about 25ft, nothing I did work. So I decided after total failure to bring everything closer together, so I set up at about 12ft and everything started working perfectly. After much testing at 70 and 200mm. I then moved back to 18ft and everything worked fine. So if you continue to get a message about "FOCUSING" please move closer to your target.

[@gavinberkey]

Thank you for this great instructional video. I followed the procedures closely to fine tune focus on my refurbished Nikon D500 with 50mm AF-S f/1.4G lens. While the focus looks really good when I zoom in on the playback image, when I compose and focus the viewfinder goes blurry. I have dialed back the diopter as far as it goes in the direction that is most helpful but it just isn't enough. Any thoughts on what else to try?

[@ConorCoen]

Thank you so much for this , I recently purchased the Tamron 24-70 G2 and I found focus soft and not all good , thankfully I remembered you had a video on this....I did it, a like patience and bang my Tamron is tac sharp 🙂

[@willionaire360]

what was your settings please. my portraits arent sharp when i zoom in

[@jamieh2239]

If you get an error message..come out of Live View. Move the focus point away from the centre and then back to the middle. Go back into Live View and the error has gone! Worked well after reading that tip on DP review.

[@mistuhgee]

I just did this on my D7200 for a Nikkor 80-200mm f2 8 af D that I got last week. I've been a bit underwhelmed. Test shots so far look sharper than anything I've ever shot! Can't wait to take it out tomorrow!! Also, going to fine tune my other lenses. So....Thanks!!

[@adampakenham1629]

Hi Steve and hello from the U.K , I'm just about to take delivery of my D500 and 200/500. I think I'm going to be asking you many question and reading many of your guides. I've already purchased the Secrets to stunning wildlife and it's fantastic.

[@christosphillips3568]

Steve thanks for the upload, always a gentleman and keeping your promise, Although the content is satisfactory, I would highly recommend anyone to download the E-book. I have it and let me tell you its the MOST comprehensive guide on autofocus for Nikon anyone could ever wish for. Really valuable reference always at hand for ANY query anyone might have , amateur and pros alike. Simply the best. Again thank you Steven....you sir are precious and a breath of fresh air in a world full of KZbin trash. Well done.

[@backcountrygallery]

Thanks so much for the kind words :)

[@PPMOCRG]

Christos Phillippou I agree, I bought it yesterday and already have learned a lot about some really useful functions.

[@richardcoward7234]

I agree. I tried to do a bit of DIY tuning but didn’t read or view this video properly and so all of my ‘test shots’ are completely wrong. Note to self (and others), R-T-Flipping-M and W-T-Flipping-Video properly next time and you’ll save yourself a lot of wasted time!

[@wahabdilawar]

Every new upload from you convinces me to get a D500.

[@RobertDuttonFineArt]

Hi Steve, brilliant production again and just what I needed to have - an actual 'how to' action video for this topic you cover in your most excellent, well written ebook. Thanks so much for creating this. Makes a MASSIVE difference.

[@tench1970]

Hi Steve, I have a D7200 and wanted to check to see if my camera is focusing correctly. At the begging of this video it mentions that this video is not for a D7200. I have tried to find your video on the alternative way of doing this on my camera. Can you post a link to this please, I am unable to find it. Cheers Steve

[@Metal4everYAY]

Can I use this auto af fine tune to actually put the calibration values for a sigma 500 f4 at different distances with the usb dock? So I am suggesting that say I need the value at 3,5 meters then I find it out with the auto af fine tune and then I input the result with the dock (of course in the end the body will have a fine tune value of 0 as the lens will have all the necessary info already). Thanks for the video in any case 🙂!

[@phonggeomin]

I've received a notice "Auto AF fine-tune is not available at current focus setting"

[@cheny8923]

Hi Steve, i notice only my primes work with auto AF fine tune my zooms keep getting a fail error message

[@richardcoward7234]

Same here on a Nikkor 200-500 f5.6. I had re-run the video numerous times to make sure I was doing everything right but to no avail. Then I took note of the comment about having a very sturdy, rock-solid base and to 'very carefully' press the two buttons for the Automatic AF-Fine Tune process without moving the camera. Mine jumps around loads! I tried to do it several times but I cannot hold it still enough to get even one pass of the AF-FT test. I am now working on the assumption that it is this movement that may be causing the failure, which is backed up by other references too. At the 500mm end of the lens, even the slightest touch moves the camera which means I will have to come up with another, more rigid setup that reduces movement on those button presses. Anyone else have this problem? It's a shame this AF-Fine Tune can't be triggered remotely via a USB connection or something! I wonder how Nikon do their testing of this on the long end of their big lenses?

[@duckhanhpham4753]

Thank you so much Mr Steve Perry to learn to calculating AF fine tune for getting correct each lens I own for the sharpest focus. Before saw AF Fine tune but I am no clue on it at all.

[@santiagovanegas3812]

Great tutorial! One question though... Once I’m finished with the entire process as you have described, do I turn off (or leave on) the AF fine tune feature in my camera menu?

[@backcountrygallery]

Leave it on or the camera won't use the settings you've entered.

[@santiagovanegas3812]

Thanks so much! @@backcountrygallery

[@rigbyphoto]

@@backcountrygallery Sorry I'm so late to the party but your video was extremely helpful and much appreciated. However would you know why Nikon say "AF tuning is not recommended in most situations and may interfere with normal focus; use only when required." With this in mind I'm cautious about leaving AF Fine Tune switched on for the few lenses that I've not yet calibrated.

[@backcountrygallery]

@@rigbyphoto It's possible (although I've never seen it happen) that a severe AFFT adjustment could prevent the lens from focusing at infinity. That's why they say it. Although, I do tend to agree with the "don't use it unless you need it" sentiment.

[@rigbyphoto]

@@backcountrygallery Many thanks. Your help is very much appreciated.

[@mitchanderson2569]

Hey Steve, thank you for this brake down! I just upgraded from the d3400 to the d850 and I just finished fine tuning one of my lenses. Now just one question, do I leave the af fine tune on or off once I have completed the process? Oh and BTW it averaged out to -5.3.

[@larrycrain4505]

I used Lensalign to calibrate my Tamron 24-70 2.8 lens came out with a -12 on the 24mm end and a +10 on the 70mm end any advices on what to set it on or is that to far out

[@mallred4347]

Hi Steve - Great video. Makes me want to sell off all my Sony gear and pre-order a D850 & Nikon primes. Thanks again for the great video!

[@backcountrygallery]

That's the sprit :)

[@mvpro2k8]

You can flip the screen and use touch instead of OK button that pushes the camera forward. Touch screen requires very minimal physical contact.

[@backcountrygallery]

Good point for the D850 - but the D5/D500 don't support touch for menu items like that.

[@mvpro2k8]

I guess I got spoiled to quickly by d850. Did not know d5/d500 lack this menu touch feature.

[@markdstump]

I did use the touchscreen, I think its a great suggestion, but the flipping it out part I consider unnecessary.* *I do baby my gear and I had previously decided to leave my screen the way it is except for those times when I think the contemplated shot is "sponge-worthy."

[@ronschmitz1521]

This solved my problem when I tried it on my D850. Thanks so much for the tip.

[@aaronsuek]

Does the correction value stored in the camera need to be manually reset back to 0 for each of the 12 tests, or does it automatically do this when you do each run?

[@ReinkeDK]

Thanks for the nice clarification on how to do the fine tuning :-) maybe i should finally read your e-book :)

[@a2roland]

Awesome!... Thank You!

[@Freddy2Noel]

Steve, I am glad I have bought both your eBooks as they are extremely informative, and fun to read with so many funny quotes keeping the reader interested. All your videos are awesome. Thank you for sharing so much with all Nikon users.

[@hamzatatta952]

hi steve how do you know when do calibrate your lens or should i say that do you it as soon as you buy a new or 2nd hand lens and how much sharper have your images become do you before after pics?

[@motorsinfocus]

Great video. What about cameras like D750 without an auto AF calibration ? how to properly set it manually ?

[@krishnaraj101]

Hi Steve Could you please do the same for Nikon Z6ii as well. What ever i am doing to calibrate, always fails

[@robertbohnaker9898]

[@ezuddinamra9072]

Thanks for this video. I am always suffering with my nikon 50mm 1.4G Lems. Its gives bad focus from time to time. Gunna try your AF Tuning Method . Thanks Again.

[@TheExtraTerrestrial]

Thanks! This is a huge help! One thing someone else mentioned on a forum is, when doing this, DON'T refocus between runs. Just focus for the first AF-fine tune, and then don't focus again when repeating the calibration. Is this correct? That's the way I did it, and it seems to have worked.

[@Gillan1956]

I have tried to Fine tune my lenses. I always get the massage Auto AF Fine Tune Is Not Available At the Current Focus settings. I look up the settings in the manual and they are the same as you told in the video.

[@WIDGI]

Frustrating, isn't it?! I eventually discovered that I hadn't pressed the centre button of the multi-selector, this ensures it's using the centre focus point while in LiveView! If that isn't it, check you're in Normal-area AF, I still had it on Pinpoint once.

[@shang-hsienyang1284]

One of the reason I bought the Sigma 150-600 Sports over the Nikon 200-500 is because I can't put different calibration values at different focus length. At the time of my purchase, Tamron lenses also lacked the support, but they've added it now.

[@arpinkus]

Great Nikon AF fine tuning vid. I originally bought the book for my D500. Then, when I picked-up a D850, Steve had already updated his book to cover that body, too. Highly recommend!

[@lesgagnon8740]

[@vameza1]

Hello, great tutorial. Just one question remained? When finishing the proccess, we need to turn the auto tune option off, right???? Thank you!

[@backcountrygallery]

You have to leave AF Fine Tune turned on or the camera won't apply the adjustments when you attach the lens. Auto Fine Tune should be off once its input the value.

[@vameza1]

@@backcountrygallery Thank you very much. Please, just one more question....I tried used the method with my Nikon D750, but, unfortunatelly, when I tried push AF button together with recording button, the notice of Auto tune didn´t appear. Do you know any issue related with this model??? If I use the scale, manually, it´s work as well?? Thank you again and best regards from Brazil!

[@backcountrygallery]

@@vameza1 The D750 doesn't have Auto AF Fine Tune, it's only on the newer cameras (the D780 has it, for instance). It still has AF fine tuning, but you have to do it manually.

[@robs7261]

@Steve - Can you please clarify (or anybody else) for me, we have a Tamron 100 - 400mm and the main subject type we photograph are military (airborne) aircraft and them at UK airshows. However, as we can only tweak and set one focal length as you state in your video, what happens to all the remaining focal lengths within the lens for instance please... will they continue to work just as one would expect, if say a little soft not being a dear lens or prime etc - OR - If I set up Auto AF Fine Tune to be the best possible on the longish end (i.e. 350mm as we don't tend to get decent shots from maxed zoom focal length anyway) will this affect all other focal lengths throughout the 100-400? Many thanks.

[@vorticity4]

Steve. Very nice tutorial and a ton better than one of your competitors who set his camera on a wood block outdoors, focused on a telephone pole, and took the resultant value after one shot. In your next update, recommend you talk about how the D500 saves the values for up to 20 different lenses and, if AF Fine Tune is ON, the camera will make the Fine Tune correction automatically when you change lenses.

[@SILBERTOR]

I'm confused. Other photographers on youtube told us, that "fine tuning"must be done using viewfinder and not live view screen. That is also my first question. My second problem is; I have good focus on 24mm end and bad on 70mm end of Nikon 24.70mm. How to solve that problem??

[@peterallen7166]

For your first question, use live view to make sure your target is centered. You can fine tune the focus if it is needed. In addressing the second question, you need to find a happy medium with zooms. I have a new Nikon 24-120 F4. AT 24mm, it sucks. At 70 and 120, it is great when I set the AF at +5. 24mm sucks no matter where I set the AF range. I had to compromise to be happy with the 70 and the 120, and get the best bad 24 mm I could.

[@KanonMadness]

[@Hodenkat]

At 07:23 you say "carefully focus on the target in live mode". Does this mean allow the autofocus system to acquire focus? How is this going to calibrate a new setting? Won't it just lock-in the errant focus setting? I'm confused.

[@backcountrygallery]

Live View doesn't use the PDAF sensors and instead uses contrast detection (usually more accurate). So, if you have a lens that Beverly front / back focusing with viewfinder AF (PDAF) and then use live view to focus, you'll find the lens is accurate. What this system does it to look at where focus should be compared to where it thinks it should be and make the adjustment.

wonder if auto af tune is just as good as manual (or with reikan, before i got d500 i used reikan for years)... btw, i once saw that sometimes af becomes sligtly off in lower light *and* with af assist (eg d600/df), guess you may need to calibrate in lower light *with* af assist if you work a lot in ll (as i do, tango parties, i use external af assist on df just to help to its crappish af, flash with af assis is no-no for me)
