This Tiffen Video Essential DV Kit contains the following filters: Tiffen Circular Polarizer, Clear, Warm UV-17, and Soft Pouch.
Circular Polarizers
Light
rays which are reflected become polarized. Polarizing filters are used
to select which light rays enter your camera lens. They can remove
unwanted reflections from non-metallic surfaces such as water or glass
and also saturate colors providing better contrast. The effect can be
seen through the viewfinder and changed by rotating the filter. The
filter factor varies according to how the filter is rotated and its
orientation to the sun. Filter factor is between 2.3 and 2.8 (approx.
+1.3 stops).
Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems).
Clear Filters
A clear (colorless) filter for color as well as black and white films. Also serves as a permanent lens protector.
Warm UV-17 Filter
Haze
(UV) filters are wise initial investments. They help protect your
valuable investment from dust, moisture and scratches, which can lead to
costly repairs. If desired, they can be left on the lens at all times
for protection. Haze filters provide additional benefits of correction
for Ultraviolet (UV) light which can register on film and videotape as a
bluish cast and can obscure distant details. Ultraviolet filters allow
you to correct for the UV effect to varying degrees.
UV-17 filters absorb approximately 97 percent of UV rays.
