To calibrate your lenses, set your camera up on a tripod, or flat surface like a table, and set the focus pyramid on a level surface about 6 feet away. 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.

What does it mean to calibrate a camera lens?
Lens calibration, also known as autofocus calibration, is a method of fine-tuning where the focus point falls in your image when you are autofocusing. Theoretically, autofocus should always produce sharp images, with your chosen subject in focus. “And lens calibration corrects how ‘off’ the lens is.”.
How is a camera calibrated?
The calibration process involves taking a series of photos in a controlled way, so you can see exactly how your focus is off. You can then correct it using your camera settings. If the intended subject of your image is blurry, that means your camera is either back focusing or front focusing.

Camera calibration is needed when: You’re developing a machine vision application (measuring objects) and therefore a good estimation of the camera parameters is required to to correctly measure the planar objects. You just want to measure the amount of distortion introduced by the lenses. Any other reason.
Why is my lens not sharp?
As I noted in the introduction, a lack of sharpness can be due to the aperture, shutter speed, or ISO settings. In the case of aperture, if your depth of field (the area of the image that’s in sharp focus) is too shallow, you might find that your subject isn’t sharp, as seen in the image above.

Do you need to calibrate lenses with mirrorless cameras?
Do you need to calibrate a mirrorless camera? No, lens calibration is not needed with a mirrorless camera and lens. This is because mirrorless cameras do not use an autofocus chip. Instead, the camera’s sensor does both the focusing and the imaging, so there is no room for miscommunication.
How do you know if your front or back focused?
Look at the middle battery – the one you focused on. This should be sharp, and the battery in front and the battery behind should be blurred and out of focus, like this example below. If it looks more like this (with the battery in front of the one you focused on more in focus) then your lens is FRONT focusing.
