Although you are able to perform the calibration whilst hand holding the camera, we do recommend for accuracy and best results that you use a tripod and affix the focus chart to a large flat surface such as a wall.Whichever method you choose, the first step is to move the camera to be close to the focus target and then press the C button on the R1 Controller to confirm that you are ready to begin.With that done, pressing the A button on the R1 Controller will move the lens focus position to its minimum point and you should then move the camera until the image is in focus.When you are satisfied that the image is in focus, pressing the C button on the R1 Controller will cause the AFX to take a distance reading to match to this focus position. If you have made an error and wish to move the camera for better focus, pressing the Cbutton again will take another reading.When you are ready, pressing the A button on the R1 Controller will move on to the next CALIBRATION POINT and you repeat the process of moving the camera and pressing the C button to capture the distance. This process is repeated until you have reached the maximum focus position of the lens.
