Thank you Toine for explaining this. This helps to clear some areas of my ignorance about panoheads.
I guess, a panohead (or the circle in this case) should have the marks that correspond to a particular FOV (or focal length+crop-factor) of a particular lens/zoom lens position.

The horizontal is field of view is allways 360 deg with a pano head. You need 3 to 14 shots to complete 360 degrees. - The camera/lens must rotate around the nodal point - You don't look in the viewfinder: level the camera/lens with the spirit level, take a shot and rotate the head to the next click stop. In this case rotate the arrow on the monopod to the next marker on the circle. The camera must be on manual everything (exposure/focus/WB). If you do all this handheld the stitching errors are a major problem.
