lens calibration chart

This is not to say that I would rather have a camera with badly aligned AF sensor than a badly calibrated lens. 4. The scales are online in printable versions. Well, there are actually several possible reasons: 1. It showed good sharpness at between 5.6 – 7.1 and just average at 8 and 9, dropping precipitously into the “below average” category at 10 and smaller. And then taking the lens and focusing at infinity might require no adjustment. Note that not all cameras have lens calibration settings. Whereas, for a prime lens like Nikon 85mm f/1.8G, I would fine tune at f/1.8, since that’s the aperture I typically use the most on that lens. With high resolution cameras like D800, using this method can yield unpredictable results, since fine tuning has to be very precise to get accurate results. This is fairly clear. 99. You can find out if your camera has this feature in your camera manual. Most prime lenses, especially above the “standard” range of 50mm have very shallow depth of field at close distances. Another free/DYI method is to use your monitor screen with a test chart image, which again can be problematic for proper testing. While landscape and architectural photographers might not care about focus issues (since they photograph at very small apertures that hide small focus issues), portrait, event and wildlife photographers are typically much more worried about focusing problems. PL provides various digital photography news, reviews, articles, tips, tutorials and guides to photographers of all levels, By Nasim Mansurov 170 CommentsLast Updated On April 17, 2020. Thanks to the patented leveling method that Michael Tapes developed, leveling your camera is easy – you just align the red dots on the back of LensAlign with the holes on the front, so that it looks like this: Place your camera at a certain distance, depending on the focal length of the lens. But the function isn’t automatic–you basically have to dial in the calibration settings. How do you get it to be perfectly perpendicular to the target? With the release of new, high-resolution cameras like Nikon D800, it seems like calibration is becoming an important and hot topic. The third method is to use an automated/semi automated software calibration tool that can save you time and possibly yield better results. Using a third-party lens that may not be fully compatible with the camera. The SpyderLensCal Autofocus Calibration Aid from Datacolor is a focus test chart, designed for use with select DSLRs that support autofocus adjustment. To know what settings to dial in, you need to visually test the camera. But if it is anything extreme (my D800E was really bad and required -20 and higher to work with my lenses), then I will surely either exchange the camera, or send it to manufacturer for tuning. Are there alternatives to sending it to Canon for adjustment? If you are an advanced DSLR user, you will typically know right away when there is a focus problem. Then, on the same page, they go on to give a similar procedure using a ruler for determining the correct AF Fine-Tune setting. An important fact to keep in mind, is that calibration is camera and lens specific, which means that if you have multiple cameras and lenses, you have to fine tune autofocus on each camera, for each lens you own (unless you have a camera that constantly front-focuses or back-focuses by the same amount with all lenses, in which case you might need to compensate only for the camera itself). This is my observation, although more in-depth testing would have to be carried out to confirm this. Adjust#by#lens 2. I then set desired ISO, aperture, and shutter speed. There are various opinions whether a chart should be viewed at 45° from the lens centerline axis, or at 30°, or any angle or even flat. So, what tolerance levels for calibration are acceptable? You should be in an environment where there is a lot of ambient light, so preferably, do this outdoors in daytime. I used an alignment fixture stand to fix my D750 to be parallel and the lens to be perpendicular to the target in the Z-axis.. The third chart (Chart-3) is for lenses that cannot focus very close. There were inconsistencies in accuracy and repeatability. Just have to say thanks for writing this. I placed all the images side by side and the -10 was dramatically sharper than the other brackets. I usually set it up at a distance that I typically shoot from, that way I know it’s accurate at the distance I shoot at the most. Again, you should be in an environment where there is a lot of ambient light, for autofocus to work properly. A slight focus issue might not be as noticeable on a 10-12 MP sensor, but will be much more noticeable on a 25+ MP sensor (assuming both sensors are of the same size). The cut-out-and-fold-into-a-box part has been done away with. If I see any drastic changes in autofocus behavior and AF adjustment does not work consistently anymore, I contact Nikon and send my gear in for repair. I bought the FoCal Pro software and it seemed to do a good job. I am sure you would not want to have such problems, which is why I encourage you to test your gear and fine tune it for optimal results. The distance between the camera and the chart should ideally be around 50 times the focal length of the lens - for example, with a 50mm lens you want to be 2.5 metres away from the chart. One could keep enlarging the last chart, but I believe that the three charts attached herein will be functional for the majority of lenses. When testing cameras with autofocus problems (with perfectly calibrated lenses), dialing a value for “AF Fine Tune” would often work for any distance, whether close or far. That’s where a tool like LensAlign can come in handy – you will not only know right away if there is a problem, but you will also determine if the focus problem is related to back-focus or front-focus. If focusing is accurate, the ‘0’ on the lens calibration chart should be the sharpest point on the image. Three lens testing charts are used here, but you can put one at each corner if you want, and the charts can be rotated if you wish. The reason why you want to do this, is because Phase Detection Autofocus is often not consistently accurate if you just rely on one exposure. Hence, the need for a properly calibrated camera setup today is bigger than ever. So…according to Nikon, one should not accept this situation as normal, and simply make an AF Fine-Tune adjustment and continue using the same lens. Mount your camera on a tripod and place it at a certain distance right across from the chart, depending on the focal length of the lens. Great article. At the end of the day, you want to get the best out of your equipment. Here is an example of a properly tuned setup using the Nikon 85mm f/1.4G lens (no sharpening was added to the image): Once you get consistently good results using a particular AF adjustment setting, take your camera for a real test. Canon camera systems and lenses are manufactured to extremely high precision standards for the ultimate image quality. I am switching to manual focus in between each AF value change and setting lens out of focus then switching back to AF-S with single point (center-point) focus and doing a mirror-up exposure but get exactly the same backfocused image?? I learned so much! Datacolor SpyderLensCal. The camera tells the lens something like this: “aim at where you would normally focus, except slightly move the focused point closer to the camera”. Focus on the circular pattern on the left side of the ruler with your center focus point looking through the viewfinder and take a series of pictures. This means the calibration value can't be adjusted for either end of a zoom. I have the AF Fine-Tune turned ON and can see this is lens in the List saved values list but when I change the setting from -20 to +20 and all points in between I get absolutely no change in the image – still same amount of backfocus. I set the distance of my 85mm to 10 ft. To my surprise the focus point was dead on with both lenses. Knowing this, if I receive a faulty camera, I know if there is a problem right away. That way, you force the AF system to reacquire focus each time. Physical calibration of lenses should only be performed by manufacturers, since lenses have to be disassembled, tuned and reassembled. I had focus problem on my D600 . The setup process is pretty straightforward, as explained in detail below: Pick a spot on your … None of them have the built-in alignment tool, because Michael patented it. Make sure that the camera is recognized by the software. Try again. In this case the corner charts are placed at the corners of a 15" x 22" rectangle. In addition, I strongly recommend following these tips every time you purchase a camera or a lens in order to identify and address any potential focusing issues. The worst problems were when both a camera and a lens had issues – that’s when trying to calibrate the setup could yield strange/inconsistent results. 11) The Usefulness/Uselessness of Camera Calibration, The Usefulness/Uselessness of Camera Calibration, how to test your DSLR for autofocus issues, Lens Filters Explained - New Video Released, Tips for Photographing the Great Conjunction. Ideally, I want to stay in the ±5 range, but if fine tuning takes care of the problem, I do not bother sending my gear to manufacturer for tuning. Confirmthe#images Perform%AFMicroadjustment% 1. Download the focus chart This focus calibration chart can help you test the accuracy of your SLR camera's autofocus, and find the right focus micro-adjust setting if your camera has that feature. Here is a sample image that I got with a badly calibrated lens: Next, you have to turn AF Fine Tune / Microadjustment on and set a value to compensate for the focus problem. Wider aperture resulting in shallower depth of field also put increased demands on accurate construction. See some of the additional notes on calibration below. The lens z-axis must be perpendicular to the target. So I thought what I could do to eliminate the chances for error before making adjustments. Once the software shows you a green checkmark, start the automated test process (Canon DSLRs only). A while ago, one of our readers asked me “how come we only get -20 to +20 for AF Fine Tune, why doesn’t Nikon allow much bigger values like -50 to +50?”. FREE Shipping by Amazon. If any number above the 0 is sharper, then your lens is doing something called back focus. AF Fine Tune currently only writes one global value per lens. Make sure that the chart is parallel to your camera and that nothing is titled. The other numbers should get blurrier as you move away from the ‘0’. with a procedure for running a set of calibration chart images through the tool to generate a lens correction profile (LCP). 6. Good luck and please let me know if you have any questions in the comments section below. More on this below. It is the best I have come across on lens calibration. Lens calibration is a complex topic for many, so my goal is to make this guide as simple as possible so that you could manage the process by yourself, while fully understanding the entire process. The process of manual lens calibration using LensAlign is pretty straightforward, once you understand what to do and do it a few times: As you can see, there is a rather severe problem with autofocus here – the left side of the LensAlign tool is out of focus and by looking at the right side, you can tell that my setup is backfocusing quite a bit. To put it differently, dialing a negative “-” number will move the focused point closer to the camera, while dialing a positive “+” number will move the focused point away from the camera. As of today, all entry-level, upper entry-level and some semi-professional DSLRs do not have this capability. How frustrated would you be, if you focus on someone’s eye and you get their nose or ears in focus instead? The bad news is that this very important calibration feature is only available on higher-end DSLRs, because all manufacturers consider it to be an “advanced” feature. On top of that, fine adjustments at very close distances are much more granular than at longer distances. You should ignore 'crop factor', a camera with smaller sensor size does not change the distance used for calibration. Really helpful article . So what happens when you dial -5, for example? Once I had the setup on the alignment fixture stand, I set the distance for the 35mm lens at 4.5 ft. In general, the calibration applies to a specific lens, so you can save different settings for different lenses. THANK YOU! To calibrate the lens, turn Live View mode off and go to your camera's menu. For this lens to land perfectly in focus, I had to dial -12. Physical damage to certain parts of the lens. Filed Under: Tutorials Tagged With: auto focus, Calibration, Crafty Cams, focus, focus calibration, Lens Calibration.

Here is a list of current Nikon DSLRs that have the “AF Fine Tune” feature (as of 10/08/2012): I will not bother listing older/discontinued cameras and cameras by other manufacturers, because the list would be too long. Therefore, over time small movements in components caused by frequent or heavy use can result in tiny changes in focus accuracy that the … Shoo+ng#environment#for#the#adjustment#test 2. Due to the nature of the phase detect autofocus system that is present on all SLR cameras, both cameras and lenses must be properly calibrated by manufacturers in order to yield sharp images. My Nikon D810 don’t focus on left hand side of the frame even the subjects in same line, try narrow F stops as well. The basic premise of a chart like this is that when photographed at anangle, the paper slices through the plane of focus. 2. Nasim Mansurov is the author and founder of Photography Life, based out of Denver, Colorado. The process of calibration involves going through a specific camera setting that allows fine tuning autofocus operation of lenses, which means that we will NOT be changing anything on the actual lens. A firmware update that is not friendly towards third-party or older lenses. 4.2 out of 5 stars 208. I know it is a lens specific issue as I also dropped on a Nikon 70-300 and shot the same scene and it is tack sharp. There are a number of free and commercial tools for calibrating / fine tuning lenses. The process with automated lens calibration is a little different. Hence, my conclusion is that if you find that your camera/lens setup requires high adjustment values (negative or positive), you might not want to mess with the whole thing and send your gear to the manufacturer for proper tuning instead. We’ve got a downloadable lens calibration chart to make this process easier. Step 2: calibrate your lenses – for non-sigma ART lenses. The camera sensor must be parallel to the target.

See if the finest details of the focus chart are in focus. The painful part of this process is that there is a lot of going back and forth, since you have to rack the focus ring 3 or more times each time you change the AF adjustment value. Select the widest available aperture and take a photograph of the chart. For example, a 50mm f/1.4 lens at 4 feet might require a -5 adjustment. The last step is to verify if your calibrated setup works reliably at different distances. I apologize if the article is too long. For example, a superzoom lens like Nikon 28-300mm f/3.5-5.6G VR can go from 28mm to 300mm and its aperture changes from f/3.5 on the short end to f/5.6 on the long end. Second, you should try calibrating your camera/lens. A straight indoor wall will do. Very well written and easy to understand. Because calibration can only be done for a certain focal length (on some lenses with a severe case of focus shift, I would recommend to even pick a single aperture to fine tune), which focal length would one pick to fine tune? The test chart itself is unchanged from version 2.0. I have the Tamron Tap-In Console which allows for focus tuning at 5 different focal lengths on my 150-600mm G2 Tamron lens.. Have youThanks considered revising the article to reflect the effects of these new focus tuning devices? Why is there a need to calibrate lenses? The same goes for lenses…. You would have to either go with a focal length somewhere in the middle of the zoom range, or pick the most commonly used focal length to fine tune. However, in many cases it is the end-user fault or an issue with camera technique that yields soft images, so I always recommend to use proper ways to identify focus problems. One big catch with the calibration process, is that it may vary by distance. © 1996-2020, Amazon.com, Inc. or its affiliates. Instead of showing 0 in focus, it is far off somewhere at 12 in the middle section of the ruler. Test and make sure that everything is operational. Another observation that I have after a number of years working with cameras and lenses, is that camera calibration only works reliably well at small adjustments, when it is not extreme. Read more about Nasim here. Furthermore, only the center point can be calibrated - the camera assumes that the calibration at the factory ensures all points are consistent with one another and, importantly, the center point. You don’t need to have this type of chart to complete the process. It is now much easier to use and it produces more detailed information. As you can see, the left side of the LensAlign tool is in perfect focus and the ruler on the right side confirms this – the focus point is right number 0. In my opinion, it is important to know and understand all the details of the process, including possible outcomes before deciding to touch this feature.

Test it at different distances and see if you are getting consistently good results or not. First, you should identify if there is a focus problem. If they don’t, then go back and try the same test at a different distance and see what you get. Whether you like it or not, autofocus precision of your cameras and lenses can change overtime. I ran some practical tests afterward and I now have ALL my lenses performing at peak performance. I have done a number of tests to show examples of this behavior (will be posted in a separate article later). For example, Nikon calls its lens stabilization technology “Vibration Reduction” (VR), while Canon calls it “Image Stabilization” (IS) and even Tamron, being a third party lens manufacturer for both Nikon and Canon, chose a different name for the same technology – “Vibration Compensation” (VC). Will it happen again after the calibration? Mount the test chart on a flat surface. Or just a plain stupid autofocus system that is always inaccurate… But I have to warn you – this article is NOT for beginners. One of the free/DYI methods involves printing a bunch of lines on a piece of paper, then setting up your camera at a 45 degree angle and taking pictures.

Generally, I decrease the number in increments of 5 first, then do additional fine tuning if necessary. The software became increasingly popular on Nikon cameras lately, thanks to the whole Nikon D800 Asymmetric Focus Fiasco, because it can clearly show which focus points are accurate and which ones are not, as shown in the below image: Here is the process of calibration using FoCal Pro (the software package we recommend): If you have a Nikon DSLR, you will have to use the Manual Setting Change (MSC) mode, where the software will tell you what to change on the camera and you will have to dial the values manually (until Nikon DSLR support becomes available in a future release), as shown in the following image: The cool thing about the FoCal Pro edition, is that it allows you to also find out what aperture is the sharpest on your lens and as I have already pointed out above, it can also analyze each focus point of your camera for precision. If you just got your first DSLR, you might get very quickly frustrated with the calibration process. Z6ii vs. Z7ii which has better tonal gradation? I personally do it a couple of times before and during the wedding season, to make sure that the gear works as expected. While I was weighing the merits of the various methods of performing calibration — I have a 50mm 1.4D Nikkor that appeared to be less sharp than any of my other lenses, I just applied a bit of common sense to achieve a no cost solution. It's designed to be printed out and stuck onto poster-board, to make an accurate free-standing focus target. Unfortunately, a number of photographers and online resources blindly recommend taking different approaches to lens calibration without fully understanding how autofocus system works, which leads to more frustration and unhappiness from end users. By checking this box I consent to the use of my information, as detailed in the Privacy Policy. Great technic for the Prime lenses only But not workout with the zoom lenses . Well, the AF fine tuning system is not that smart to be able to cope with all these variables and therefore calibration values might have to be different at various focal lengths, apertures and camera to subject distances. If you suspect that your modern SLR or SLR lens has autofocus problems, youcan use a chartlike the one offered on this page to perform some tests. Camera & Lens Focus Matching. 4. It's important to use a distance that will enable the lens to work well for a variety of distances not just the one picked for calibration. I am aware of the fact that there are other tools similar to LensAlign. 5. In addition, you might need to periodically re-calibrate your camera gear (more on this below). While testing various Nikon DSLRs during the last few years, I came across a couple of camera bodies and lenses that had severe back/front focus issues, where something like -20 adjustment had to be dialed during the calibration process. If the camera has a slight issue, it would not bother me, since I could dial one setting for all lenses. "Adjust#by#lens"#and#"All#by#same#amount." I printed your test chart, hung it as described, and bracketed corrections as follows: -10, -5, 0, +5, +10. The way calibration works, is the camera has a setting, which allows compensating for either back-focus (when focus is shifted behind the focused area) or front-focus (when focus is shifted in front of the focused area). In cases where a camera body was at fault, the impact of an extreme adjustment did not seem to be so bad (although it was still not very reliable), while when a lens was at fault, dialing above -10 or +10 (especially above ±15) yielded very inconsistent results. I have tried a number of different methods and I have identified which ones work and which ones are unreliable. On some lenses, the difference is very noticeable, while on other lenses differences are too minor to notice.
