How do I calibrate my camera lens?
To calibrate your lenses, place your camera on a tripod or a flat platform such as a table, and place the focus pyramid on a level surface approximately 6 feet away from your camera. I normally set it up at a distance that corresponds to the distance from which I regularly shoot, so that I can be confident that it is accurate at the distance from which I shoot the most.
Why is my lens loose?
If your lens pops out, it’s possible that the screw has become misplaced or has become loose. It’s essential to have the original screw or one that fits within the hole on hand if you want to put the lens back in its place. In addition, you’ll need a jeweler’s screwdriver. In any other case, carefully insert the screw into the hole, but do not tighten it.

If the focusing is accurate, the point on the picture that corresponds to the number 0 on the lens calibration chart should be the sharpest spot on the image. As you travel away from the ‘0,’ the other numerals should get increasingly blurry. If any number over 0 is sharper than the previous one, your lens is performing a technique known as reverse focus.
Why is my macro lens not focusing?
