Maximum Aperture Indicator
As the lens' aperture ring is turned to the maximum
aperture position at the completion of lens/finder cou
pling and indexing, the finder displays the lens’maximum
aperture via the indicator (see figure below). For ex
ample, a lens with a maximum aperture of f/2.8 will
cause “2.8” to appear in the finder’s maximum aperture
indicator when properly coupled. The scale is provided
with numbers (and dots for intermediate settings) of
from “1.2” to “5.6” as depicted.
