Apertures and Click Stops

Certain lenses have a white dot next to the maximum aperture. The white dot indicates a difference of one aperture stop. For example, as shown on the right, the white dot next to f/2 indicates f/2.8.

If there is no white dot for a click stop between the f/numbers, the click stop indicates the respective f/number shown below. Also, certain lenses have no intermediate click stop at both ends of the aperture scale due to a lack of space. Do not set the aperture ring to a position where there is no click stop.
