About the Iris F-number
Blurry effects due to "small aperture diffraction"
may occur when the diameter of the iris becomes
too small. When this phenomenon occurs, the F-
number on the screen turns gray to warn you that
the diffraction F-number of the iris has been
exceeded.
You are recommended to make appropriate use of
ND filters to prevent the F-number from turning
gray.
