filter 1 reduces the volume of light to about
1/4, and ND filter 2 to about 1/16.

indicator. If
FILTER switch to 2 to turn on the
indicator. If
FILTER switch to OFF to turn off the
indicator.
b Notes
• If you move the ND FILTER switch during

recording, the picture and sound may be
distorted.
• If you adjust the iris manually, no ND filter
indicator will appear even if the ND filter

in a fuzzy focus (this is a common phenomenon
with video cameras). The ND filter suppresses
this phenomenon and gives better recording
results.
