Brightness Control
You can set the amount of brightness you want by turning the aperture adjustment ring when
using your lens.
When you turn the aperture adjustment ring between 22, 16, 11, 8, 5.6, 4, 2.8, 2 and 1.4 you are
making 1 stop each turn. Brightness can be set more precisely by making half stops as well (see
below).
5.6 and 8 are 1 stop apart (1EV).
