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.
Setting the Gain
This function electrically boosts the light sensitivity
when there
is insufficient illumination on the object.
You can set the gain of the video amplifier
according to the brightness of the object. Select the
setting mode according to your shooting
conditions.
