    Very useful, thank you!
    For those who don't know, AF fine tune only works when you use viewfinder to auto focus. If you use live view to auto focus, it won't do anything. When I fine tuned my 85mm 1.4G, it went from -3 to +19 on saved value, probably because I did it at night without enough light. So, I fine tuned it manually, by changing the saved value. To do this, you first use live view, I use AF-S, AF area normal, 1/100 shutter speed, f/1.4 and ISO enough to get normal exposure (2000-3000 I can't remember), use delay exposure set to 3s and self timer set to 5s to eliminate some of the camera shock, then focus on the target and take a picture (your camera on tripod always). This should be the optimal focus, your goal is to get a picture with viewfinder auto focus close to or match this picture. For viewfinder settings, I use the same settings as live view. I went from +1 to +6, and +5 was the best when I took a pic with viewfinder. The reason why viewfinder and live view auto focus are different, is because they use different auto focus systems, Phase Detection for viewfinder and Contrast Detection for live view. You can google this for more info. I was frustrating before fine tuning the lens, thinking if I wanted the best auto focus, I would have to stick with the slower but more accurate live view auto focus. Now after fine tuning, the viewfinder auto focus is just as good, if not sometimes better than live view, and with faster speed as always.

      The D850 (like all DSLRs with "live view") use a separate focus module in the light path when using the optical viewfinder (the pentaprism splits the light for your eye and this focus module.) When using "live view" it's using dedicated "focusing pixels" on the actual sensor. So there is inherently some mismatch between these two systems from assembly tolerances and other factors I'm sure.
      But it works great! I fine-tuned a rental 800mm nikor prime and was amazed at the improvement. Unfortunately the camera stores only one fine tune value per lens so with a zoom, you have to pick one"target" focal length.

      Thank you for the input and thank you for the video. so you recommend one to shoot photos from viewfinder and not live view?
      if there is a back focus, does one move + or - ? it gets confusing on the scale.
      However my main question is, what is better: lens calibration for sigma, or AF fine tune on the camera?

    Hi Matthew. I used Tamron lens(15-30 G2, 24-70 G2 and 70-200 G2) with my D850. What I happened, after several attemps of calibration and failing, I sent it to a Nikon/Tamron service agent to be calibrated. There was a problem in the nikon auto-focus system which was covered under warranty. They calibrated the lens as well under Warranty. I now normally check my calibration once a year or if I have a big trip coming up. On the my zoom lens I use the same method as you but with a little extra. I start at the longest range if the Autofocus returns say +1 then I go through all the setting using the "Dot-tune" method to find the range that the zoom is in focus say( -3 to +3). I do this for all zoom lengths to find a common auto-focus settings. I have been lucky and have always found a common auto-focus setting to suit all zoom lengths on the lens. I have had excellent results.

    I use a D500 and have some of the same lenses that you have. My Sigma 150 - 600 has never been as sharp as I'd hoped when I bought it. My other go to birding lens is a 500PF which is quite good but I noticed that if I carefully focus manually on a distant fixed object I get a very slight improvement. I'll try your calibration procedure on both lenses. Thanks.

    • @MatthewRaifman
      @MatthewRaifman  День тому

      Hey, thanks for the question. That issue with fine tuning zooms is that you can only set one value for the lens, not for each focal length in the zoom range. There are two ways to deal with this in my opinion: 1) pick the focal length you use the most and fine tune to that focal length; or, 2) fine tune it for a few values (say 14mm 18mm and 24mm) and average the values for your setting. Good luck!

    • @MatthewRaifman

      This video should get you to the process, but because you can only enter one adjustment per lens, you have to choose which focal length. I would probably calibrate at both focal length extremes and then split the difference. Or just calibrate for the middle of the image: 200mm. Hope that helps

    Hey Matthew, thanks for the tut, especially on a d850 as that's what I'll be using as well. Question: when's you do this for say 5 lenses and save the results, do these get applied automatically when you use said lens? Or do you have to go find saved x and apply it when using lens x?

    • @MatthewRaifman
      @MatthewRaifman  6 місяців тому +1

      Yes, they should be applied automatically to each lens when you connect it. However, you can only save one value for each lens. This is a limitation for zooms as you must pick a focal length to calibrate.

    Thank you very much Matthew for this very comprehensive and useful video!
    I followed your instructions very closely and I was able to calibrate a few lenses; 50 mm, 105 mm, and the shorter focal length of my 24-120 mm yesterday. However, today, I wanted to continue the process by calibrating the longer focal length of my 24-120 mm and continue with my other zoom lenses.
    Despite my well celebrated success with the process yesterday, I was not able to continue the exercise, as I consistently received the error message “ Auto AF Fine Tune is not available at the current settings” even for the lenses done yesterday (troubleshooting).
    Do you have any idea about other key elements to consider when calibrating lenses using this method?
    Other questions:
    1. For Zoom lenses, do you recommend doing only one focal length if one does not have a go-to one? If yes, the shortest of longest focal length?
    2. Do you recommend a series of tests (12) per focal length that is later averaged and manually entered as fine tune value.
    3. While the Aperture is kept wide open for each lens, should I also keep the ISO to the lowest setting (64 or 100)?
    Thank you in advance for your help with this!

    • @MatthewRaifman
      @MatthewRaifman  2 роки тому

      Glad the video was helpful. That’s odd, especially given your success before. I wonder if your lighting conditions were different on the second day. Or perhaps the AF switch was accidentally toggled? I don’t know what it could have been otherwise given you figured it out the day before.
      1. For zoom lenses, I recommend calibrating for the focal length you use the most rather than the extreme. For aftermarket options like sigma and tamron, they do allow you to do basically the same exercise but for multiple focal lengths to create a custom calibration. This requires their dock but only works for those third party lenses (and not all models either). If you really use all focal lengths of range, you could consider calibrating for the middle of the range (ie 50mm for a 24-70) however the calibration may not be linear so that might affect the wide focal length more than the zoom for example. It’ll depend on your specific lens-camera combo so you might need to do a bit of trial and error.
      2. I think this strategy will be very successful at precision but might not be worth the extra effort to be honest. If you like it, why not though because it will only help.
      3. I don’t think ISO will matter much here. It’s good to keep the lens wide open (IE f/4) both for focusing requirements and because the focal plane is smallest. If you shoot at the other extreme, ie f/22, and everything is in focus I would think it would be more challenging to assess focal calibration needs.
      All best,
      Matt

    • @MatthewRaifman
      @MatthewRaifman  2 роки тому +1

      Hi! Thanks for the question and it's a good one. For zoom lenses, if you use one focal length more than the rest (for example, 50mm on a 24-70mm lens) then I would suggest that you try to calibrate to that focal length. If you feel that you use all focal lengths equally, then it is a little more complicated. It really depends on your particular lens+camera combination and I would suggest you run the tests at three points: widest focal length, midway, and longest focal length. So again, if you have the 24-70mm, then see what values you get for calibration at 24mm, 50mm, and 70mm. If all of the values are similar (e.g. -10) then I would just set the calibration to that value and be done. If the values vary widely, then you have to either pick one or just not calibrate at all. Hope that helps! Let me know if you have other questions.

      @@krimbos1 thanks for the question. There are two philosophical approaches here for zooms. You can only calibrate to one focal length, so you can average (as you suggest) or you can pick the focal length you use most often. If it were a telephoto and you are a wildlife photographer, I’d say calibrate to the longest focal length because that’s is the most used. If it’s a wide angle, you might also calibrate to the widest angle (ie 14mm or 16mm). The average approach probably makes the most sense for mid-range zooms like 24-105 or 24-70mm. Hope that helps!

      I'd recommend you try it. There are lots of reasons why a lens doesn't focus and fine tune addresses just one aspect of it (the calibration of the lens to the camera body). I've had other lenses that were blurry due to the de-centering of the elements, for example, that wouldn't be fixed by fine tuning. To be clear, though: what I show in the video is my experience, which is 100% honest and not doctored in any way. I simply calibrated the images, took before and after photos, and showed the photos side by side in lightroom with no sharpening.

      @louispasdeprenom9950 I know this is a year later, hope you see it. Have AF tuned several Nikon bodies (D7000, D71-7200, D750 & D610) with multiple lenses, fixed FL & zoom, Nikkor and aftermarket (Tamron & Tokina).
      My experience has been similar to Matthew's: Focus tuning IS a game changer. Cameras and lenses are mass produced; tolerances are allowed in the process. Even if a given lens is a Nikkor, it may be produced in Japan or Thailand. Having shot Nikon since 1965, I have older AF lenses as well as newer ones. Almost all, from new out of the box to older, well-used glass have shown improved sharpness with focus tuning. Some have required only a small adjustment (15. All the way to 20 on some bodies.
      Most bodies I've tuned tend to skew all in the same direction - most lenses require a plus correction or most require a minus correction. This tells me that AF sensor adjustment in the camera itself is difficult to get 'perfect' on the production line. I've also seen the same lens require a minus adjustment on one body and plus on another - again, it's the body you're tuning. However, I have a couple of lenses (Nikkor zooms) which require corrections (>15) on every body, always in the same direction. In that case, it's the lens. Regardless tuning usually makes a visible difference in sharpness .
      My advice would be to carefully follow Matthew's procedures to TEST your camera(s) and lenses. If you don't see a difference return AF tuning to zero, or turn it off. No big deal. However, I'll bet that you see improved sharpness.
      Manufacturing tolerances are real - every camera, every lens is NOT identical to every other. Some, like cars, are built on a Monday or Friday ;~) or an employee had a tough day.
      We pay a lot of money for our photo gear. If AF tuning doesn't yield a visible benefit, return it to zero or turn it off. But try tuning - why leave possibly improved sharpness on the table?
      If you have more than one lens or one body, the odds of benefitting from AF tuning go way up. Don't believe a store clerk or even a Nikon rep if they tell you every body and lens is perfect, zero-tolerance all the time. They're not. I like and appreciate Nikon products. I also realize that if they were hand built, as were Leica's into the 1960's, they would cost three or four times as much.
      If you see this, pls post a reply if you try AF tuning. I'd like to know!

      ​@@meliemelaThank you.
      Somehow, five decades often seem to have passed in the blink of an eye. 😢 I would like to know where they went.... 😂😂😂
