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).
This filter is specific to Cokin's new "X-Pro" Series filter holder and rotates within the holder.
The Z-PRO Linear Polarizing filters Z160 constitute one of the major advantages of
the System. High-tech to the extreme they are inserted
directly into the first slot of the filter-holder and need no extraneous
accessories. Placed very close to the lens, they produce no vignetting
and are much better protected against reflections than when positioned
further from the lens, as with certain other filter systems on the market.
Moreover, in contrast to those “slim” screw-in polarizing filters lacking
additional threading on their exterior side, one can add another filter to
the configuration if necessary. Finally, owing to the conception of the
Z-PRO System, you will only need a single polarizing filter for all of your
lenses, current or future, up to 96 mm in diameter!
