Center Shift

this step is only available when calibrating a zoom lens centre shift accounts for the any misalignment that can happen when a lens is mounted to a camera centre shift can vary each time a lens is mounted, and it is good practice to repeat this step when remounting lenses that exhibit significant centre shift the user is guided through the centre shift process by the ui, to begin, press the “start centre shift calibration” button find a clear and fixed (not moving) feature in your environment zoom the lens fully tight and align the feature with the red crosshair displayed in the ui adjust the focus so that the feature is clearly visible ensure the pan and tilt of the camera is fixed so that the camera is unable to move at all zoom out fully on the lens visually check to see if the red crosshair has drifted from the feature it was aligned to the “ magnification magnification ” slider in the lower left corner can be used to help see any drift if the red crosshair has moved, it can be adjusted back into place using the onscreen gizmo the process can be repeated to check that the update is applied correctly
