It's a Nikon, what can I say! Actually, the reason I like the Nikon CPL filters so much is that they are easy to turn (I've had B&W and Hoya that are very stiff), they don't cause a color shift in the White Balance and they are very thin so they work well on my Nikon 16-35mm lens.

I bought this filter for my new Nikon D5100, I have owned it for one month and it has performed up to my (high) expectations. I decided to go with the Nikon after reading so-so reviews for cheaper off-brand polarizers.

This is the second one I've purchased from Nikon. I have the 67mm as well. Both work much more smoothly than my 77mm B+W. They do the job and do not get in the way.

Have been using the filter when shooting landscapes and it enhanced the picture considerably. Very easy to hit the sweet spot as I adjust it.

The Nikon polarized filter cuts out smog and brings better and brighter colors to the photos

Optics at its best!

Great for shooting water

Wonderful addition to my lens, allowing for the colors to appear rich and alive.

Shooting through glass windows and in bright sunlight

What to say? It's basically a lens saver. Having said that, it does what it's supposed to do very well. High quality glass as is expected as well as overall construction. The slim designation means you can normally slap on a slim polarizer or other filter on front of it without too much in the way...
