The price range, of course, depends on the brand, type, filter size, and the number of coatings on the filter.

Try getting e-quotes from CP or MScolor and do a comparison.

It can also duplicate as a Neutral Density Filter, by rotating the filter, you are also reducing the amount of light entering the lens. One use of the ND is when you are force to use a fast film (ISO 800) outdoor during the day. A polariser can effectively reduce the light by two stops, which will lower the ISO 800 film into an equivalent ISO 200 speed. :bsmilie:
