Brightness Control

 

You can set the amount of brightness you want by turning the aperture adjustment ring when

using your lens.

5.6 and 8 are 1 stop apart (1EV).

               

Set a 0.5 stop (0.5EV) between 5.6 and 8

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).
