Apertures and Click Stops
Certain lenses have a white dot next
to the maximum aperture. The white
dot indicates a difference of one aper-
ture 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.
