But by how much? It will take a few tries until you get the 15 centimetre mark to look sharp. After you take a photo, inspect the photo to see if focusing is accurate.
We recommend that you do this on a computer since you can see better on a bigger screen. If you want, you can even tether your camera during this process. Tethering simply means connecting your camera to your computer. That way, you can take pictures remotely and view them directly on your screen. For this you will need to:. You can either press the shutter button on your device or click on the virtual shutter button that appears on Lightroom. After you take a photo, it then appears in Lightroom.
Review the image to see if everything is sharp. Feel free to zoom into the picture. If any number above the 0 is sharper, then your lens is doing something called back focus.
If any number below the 0 is sharper, you have a front focus issue. In either case, you need to correct your lens for sharp focus. You do this using the auto-focus micro-adjustment parameters on your camera body.
On Nikon cameras , you need to look for the AF fine-tune Menu in the camera settings. You can find this by clicking on the menu button and then selecting the wrench section. Ensure the AF fine-tune is ON. As we mentioned before, our camera will remember the changes each time you place that lens on your camera. So you only need to use the focal lens calibration once for each lens. Make sure you enable the Autofocus AF Micro adjustment. Use the Adjust by lens values to correct and fine-tune your focusing.
You should be set and ready to shoot. Do this for every lens, and then again, if you have multiple cameras. I suggest that you consult your camera manual and follow the instructions to calibrate lens. The menu items and the names may be different. But for the most part, the process should be similar.
Even most entry-level options have them. As I mentioned earlier, apart from DSLRs, some mirrorless options also have this feature, but for a different reason. Calibration can speed up autofocusing. Manually calibrating your lenses is quite easy to do. But sometimes, it can be challenging to confirm whether or not the adjustments we made were precise. If you want to ensure accuracy when calibrating, we suggest you use dedicated software such as Reikan Focal. Instead of just eyeballing your adjustments, this program confirms whether the parameters you set are accurate.
FoCal comes with a calibrator which you can tape onto your wall. Once you upload the software, you can tether your camera, and the program will instruct you where to position your device in front of the calibrator accurately. The program will then start taking photos without you having to do it. Expect to hear a few voice prompts from FoCal until the test is complete. In general, the entire test only takes a few minutes.

Most photographers feel that this method for calibrating lenses strikes the best balance between DIY methods like the one below and expensive computer software.
The best DIY method i. Step 1 — Attach a piece of whiteboard to a low table or another flat surface. This will give the camera a specific focal point with nothing else in the frame. Step 4 — Set your camera settings to the widest aperture your lens will go to and adjust your shutter speed to ensure a correct exposure.
Set your central focus point onto the line you drew. Step 5 — Place a ruler or two alongside the line. Line it up on a particular mark. One ruler will work fine, but many find that working with two rulers is easier. Below you see two rulers using the 20cm mark. Pro tip: M ake sure that nothing is going to move, neither your whiteboard, your rulers, or your camera.
The sharpest number should be the one that aligns with the mark. In this case, that should be the 20cm mark, but as you can see, the 21 cm mark and even a few notches towards the 22 are sharper than the If the results are off, go into the menu and find your AF micro adjustment feature. You can see here that my lens is back focusing. While I focused on the 20 cm mark, the 21 and even the 22 cm marks are sharper.
Step 7 — Take the shot again and compare the results. Make any further adjustments necessary. The goal is to have the number aligned with your focal point be the sharpest. This time, the 20 is the sharpest number. The adjustment was successful and the lens focus is now accurate. For superior results, you can always invest in lens calibration software. The most popular is Reikan FoCal. That being said, not every user has successful results with lens calibration software.
