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. To Get Started, Simply Print Out the Chart on a Piece of White Paper or Cardboard. Place a Small Object with a High Contrast Edge, Such as a Ruler or a Coin, in the Center of the Chart. Next, Position the Object at Different Distances from the Camera Lens, Making Sure to Keep It Sharp and Focused Throughout. Take Multiple Photos of Each Distance Setting, Keeping Track of Which Focus Micro-Adjust Value You Used for Each Shot. Once You Have Taken All Your Photos, Review Them on a Computer Screen or Print Them Out and Study Them Closely. Look for Any Areas Where the Image Is Not in Sharp Focus, and Note Down the Corresponding Focus Micro-Adjust Value. By Following These Simple Steps, You Can Use This Focus Calibration Chart to Help Fine-Tune the Autofocus System of Your SLR Camera, Ensuring That It's Working at Its Best.
