(More customer reviews)If you're planning to use this polarizer with a hood on, especially a deeper one, this is probably not a filter for you. For whatever reason Hoya only serrated the outer edge, and the front part is absolutely smooth. You won't be able to turn it unless you can somehow squeeze your finger between the hood and the filter edge.
For a few dollars more you can get B&W multi-coated filter like this, whose maker put a little bit more thought in the design. B&W also seems generally better built.
The coating on my copy of this Hoya doesn't actually reach the very edge of the glass on one side, and when I look closely I can see a gap in coating where the metal ring meets the glass. The gap is tiny and it doesn't actually matter in the photos, but it does leave a bad impression.
Optically I haven't noticed anything obviously wrong with it. It's still a multi-coated polarizer, so guess it's an okay value all-in-all.

Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also saturate colors and increase contrast. Polarizers come in two variations but have the same effect. Linear polarizers work with older camera meters; Circurlar polarizers are designed for today's newer split-beam metering systems used in auto focus cameras. Check your camera's manual Extra thin filters are narrow construction with ultra thin glass. They are designed to avoid vignetting with today's larger wide angle lenses.
