Steps of use:

A. Open and set up the tool vertically.
B. Aim at the center of the circle. (For long zoom lens, aim at the big circle; for short zoom lens, aim at the small
C. Make sure the camera’s CCD sensor is parallel to the center of the circle.
D. Focus on the center of the circle and take a picture (Advise using the maximum aperture as this brings a small depth
of field so that you can examine the focus accuracy more easily. )
E. If the “0” on the scale is clear, it means the focus is accurate as this means the “0” and the center of the circle
are in the same focal plane.
F. If the “0” on the scale is not clear while it is clear on the “1” below or above the “0”, it means it is 1cm front
focusing or 1cm back focusing, in this case, you need to fine tune the focus accordingly via your camera.
