User of many polarizers in me photography life. Because I have a "wide angle" preference, I can recommend this filter for it's thinness of frame. Works great for UWA lenses.

Decided to pick up a CPL filter for those high glare shots and it's made the colors more vibrant.

After using this on multiple cameras (Cannon and Nikon) and multiple lens the results all were the same, thumbs down. The sky was blotchy in all the photos.

Polarizing effect was good. Not quite as slim as I'd hoped but didn't cause any vignetting. Used a lens cleaner (Zeiss pad) and had a hard time getting the glass to be streak free. Hasn't been something I've noticed on other glass (including other CP's). I purchased this at an extreme discount. Not sure I'd pay full price for another.

I purchased yes Polarizer because it was thin and could be used on a wider angle lens. As it turns out the filter is very thin and care must be taken when installing the filter. The first time I used it I probably tightened the filter a bit too much and I had a very difficult time removing the filter after use. The polarizing effect is excellent and the filter works great on a lens as wide as 24 mm. Now when I use the filter I'm careful to only tighten lightly so I'm able to remove it easily.

it is a very good filter. There are certainly filters that are more expensive, and probably a little better, but some of value perspective this one is tough to beat.

I happened to be in need of a new CPL and this caught my eye when I saw a few good reviews and a big discount. I snatched it up quickly and have been very happy with the product. It is incredibly thin and feels well made for a budget shopper like myself. I'm also happy that their are female threads so I can attach my ring adapter and use some grad filters.

Made well.doesn’t darken skies as much as other cpl’s i have used. That is fine with me. Colors are more natural.

I do all kinds of photography, but for landscape photography and even taking head shots of people outdoors, I always use a polarizer. Since I have so many different size lenses, I decided to buy an extra one so I wouldn’t need to stop and swap one between two same size lenses. I’d never bought a Sirui filter before and I typically by German B+W ones. But I’m really impressed w the quality of this Sirui.

I have used the polarizer on a 10-20mm lens and am fully satisfied with the images.

Polarization
The Sirui Ultra Slim S-Pro Nano MC Circular Polarizing Filter increases the color saturation of the image, meaning whiter clouds and a bluer sky, for example. The filter also reduces reflections from non-metallic surfaces (water or glass). Thanks to its high quality, the Sirui Polarizing Filter achieves a polarization rate of nearly 100%.
