Use the cameraвЂ™s timer or a remote trigger to activate your shutter. Turn off vibration reduction/image stabilization. Put the camera into single-shot autofocus mode, with the center focus point selected. Place your camera on a level surface the correct focal length away from your tool, depending on the focal length of your lens (50x the focal length for lenses under 200mm, 25x for lenses over 200mm.) Set the tool on a tripod, using the included spirit level to ensure itвЂ™s level. Rather than rely on trial-and-error to calibrate your lenses, itвЂ™s much easier to invest in an inexpensive lens calibration tool like the Vello LENS-2020 Lens Calibration Tool.

Now that weвЂ™ve got that out of the way, hereвЂ™s how to calibrate your prime lenses. Sure it will cost you, but isnвЂ™t your mental health worth something? If you have a focus problem with a multi-focal length (zoom) lens, send it back to the manufacturer for calibration. So the focal lengths that were previously sharp, wonвЂ™t be any longer! When you make adjustments to calibrate your lens, there is no way to avoid affecting all the focal lengths on the lens. This is why you don't want to mess with zoom lenses yourself. In fact, it's likely that some focal lengths are already in perfect focus. If you test a multi-focal length lens in the way I described above, youвЂ™ll soon notice that some focal lengths are sharper than others. Prime lenses are the only lens type that IвЂ™d recommend you calibrate yourself. There are certain lenses you shouldn't try to calibrate yourself.

(If youвЂ™re in doubt whether your camera has this feature, check your camera manual to confirm.)

To find out if you can calibrate your lens, look for a setting in your cameraвЂ™s custom menu called вЂAF Fine TuneвЂќ if youвЂ™re a Nikon shooter, or вЂњAF Micro AdjustmentвЂќ for Canon and Sony users.

Pro and prosumer cameras have this setting, not entry-level models like the Canon Rebel or Nikon D3500. Note that not all cameras have lens calibration settings. An adjustment of only a millimeter or two can make all the difference in achieving tack-sharp focus.

Lens calibration is a series of small adjustments made to fine-tune your lensвЂ™ focus. If it isnвЂ™t, then itвЂ™s time to calibrate your lens. (If the lens is 200mm or over, reduce this factor to 25x.)ДЇor example, if youвЂ™re checking a 35mm lens, youвЂ™d calculate this distance 35mmx50=1750mm.ДЇollowing the same instructions given in the previous test (turn off image stabilization, put your camera into single-shot autofocus mode, use the center focus point, etc.), focus on the center object.Д¬heck your photo to make sure the focus is on the center object. Position your camera on a tripod approximately 50x away from this focal length. Note the focal length of the lens you want to check. Line up five identical objects on a flat surface at 45 degrees from you (batteries work well for this test.) If the focus is on their nose, itвЂ™s front focusing. If the focus has shifted over to their ear, the lens is back focusing. (Shoot tethered to your computer for convenience if you like.)Д¬heck to see if the focus on the subjectвЂ™s eye. Now, import your photo into Lightroom and zoom in close. Focus on your subjectвЂ™s closest eye and use a cable-release or self-timer to activate the shutter. Open the lens aperture as wide as possible. To avoid camera shake, make sure youвЂ™ve disabled vibration reduction (Nikon) or image stabilization (Canon and Sony). Put your camera into single-shot autofocus mode on a tripod, with your center focus point activated (because itвЂ™s the most accurate focus point.) How Can I Tell if My Lens Needs Calibration?Д«efore you try to calibrate your lens (or have it sent off for calibration) there are two easy tests to check if your lens is front or back-focusing. It needs to be calibrated to your camera.
