FILTER WINDOW
The filter window in the lens hood provides access
to the edge of filters that rotate, such as circular
polarizers, graduated filters and variable ND fil
-
ters. This feature allows you to adjust those filters
without removing the lens hood.
To open the filter window, push the raised portion of the blind
toward the front of the lens hood, sliding the blind until it clicks
into place. To prevent unwanted side light from striking the
lens, close the blind when the window is not in use.
