I've been struggling with getting my camera to calibrate correctly with the Nodal Ninja 3. I'm currently shooting at 14mm. I've positioned the vertical arm so that the camera is positioned over the nodal point. I followed a long with a online video which I'm not sure is correct. I positioned the vertical arm so that the cameras was centered over the center of the tripod head (nodal point).
I've positioned the horizontal arm so that it aligns correctly with objects when I pan. When I tilt the camera the object appear elongated. Which leads me to believe that the vertical arm is not positioned correctly. I'm not sure where to go from here. Please share any information you may have in resolving this issue.
