Product Description

Light rays, which are reflected by any surface become polarized and polarizing filters are used to select which light rays enter your camera lens. PL (Linear Polarizing) and PL-CIR (Circular Polarizing) filters have the same effect, but it is important that you choose the correct version for your camera. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. HOYA's polarizing filters do not affect the overall color balance of a shot.

Customer Reviews

Does the job very well
A polarising filter is a must in your camera kit. I have a Sigma 10-20mm wide angle for my D60 [that's 15-30mm for full-frame] and shots with this lens including lots of sky benefit enormously.

The one thing I'd like to see Hoya do is make the index mark on the outer edge of the rim run over onto the inner edge, so that you can see it if the outer edge is masked by your lens hood. With a lens hood tight on the lens, the index should be visible from the front, not just the side-view of the filter. No probs. A blob of Tipex or similar will do the job.

Okay but not for ultra-wide angle
I purchased one of these for my Canon EF-S 10-22mm f/3.5-4.5 USM Lens - I know these filters to be fairly slim and figured it would be enough, unfortunately it's not quite slim enough and causes significant vingetting at 10mm. However this quickly disappears when you move past about 12mm so it's still just about usable on this lens; particularly if you're planning on cropping your images into letterbox aspect ratio anyway.

For the best results on an ultra-wide angle; you need a slimmer filter than this. I have now replaced mine with an Hoya 77mm PRO1 Digital Circular PL Filter - significantly more expensive, but much better at 10mm.
