NiSi, 55mm True Color CPL w/ Ultra Low Pro Nano Coating and CINE Seal Tech for Camera Lens - Circular Polarizer Filter Camera Accessories for Photography Use - Polarized Film Electronics Essentials

Returned a “true color” to buy this nisi works great and is true to color. No yellowing

I’ve never been disappointed with NiSi, good stuff

Looks good quality

I picked up the NiSi 77mm True Color CPL, and while it makes my skies pop without turning them into radioactive Smurf blue, it’s not perfect. The build quality is solid, with smooth rotation that’s easy to fine-tune, and I love how it keeps colors natural while killing glare and reflections. The downside? On my wide-angle, there’s a noticeable vignette that shows up more than I’d like, especially at the wider end. It’s still a big step up in clarity and color from cheaper CPLs, but between the vignetting and the price, I can only give it 3 out of 5 stars.

Bought for my kid. Idk. I never use it but my son seems happy and I'm happy bc it was cheap. It's lasted a long time and appears to be made well.

I like NiSi filters and they do provide me with true colors in my photos.

This is the first CPL I have ever bought. The retating ring is smooth and easy to use.

The good: It's headline differentiator is true. It's the most color neutral polarizer I've used; more color neutral than B+W, Breakthrough, Kolari, and others. I also like the knurling that is becoming common on filters. The bad: It is also unfortunately also the least effective polarizer I've used. A polarizing filter is supposed to allow through light that is polarized in the same orientation as the filter and cut out light that is polarized in the perpendicular orientation. This filter still lets in a small amount of the latter. It's also not a circular polarizer. Here, "circular" doesn't refer to the shape of the filter but rather a circular polarizer has an extra layer on the inside (lens side) to "reset" the polarization of the light that it let through so as not to interfere with certain kinds of optical systems (e.g. autofocus). A quick way to determine if a polarizing filter is a circular polarizer vs a polarizer w/o this extra layer is to flip it around so your lens looks through the outside: when you rotate the polarizer, it shouldn't be filtering polarized light differently since that extra layer should be resetting the polarization before it gets to the polarizing layer. This filter fails that test -- it is a linear polarizer. At 49mm, you're not likely to be using this filter on a camera that needs a circular polarizer instead of a linear polarizer, but it's still incorrect advertising.

安物のPLフィルターで渋谷スカイでガラス越しに撮影すると、変な影が発生します。 （ガラスのコーティングとの相性？） この商品は、そのような影が発生しませんでした。

Ya habia usado otras marcas y la verdad es que este es el mejor que he probado, los demás modificaban muy considerablemente el color, recomendado.

Ho comprato questo filtro insieme al NiSi Filtro Polarizzatore Enhance (Landscape) e devo dire che sono veramente fatti bene a livello di materiali e hanno una bellissima resa a livello di fotografia. Tutta via questo è più luminoso rispetto all' Enhance, non perde uno stop di Luce ma la resa cromatica è favolosa. Unica pecca è il prezzo. Va bene che stiamo parlando di NiSi ma anche meno con i prezzi ;)

C'est un très bon CPL mais.. ne justifie en rien son prix si ce n'est que la bague est plus épaisse qu'à la concurrence (plus facile a manier), j'utilisais un autre CPL, j'ai pris celui ci par curiosité et je n'ai aucune différence niveau résultats, pourtant 40€ les sépare, Nisi est une valeure sure, mais si vous faites attention à votre portefeuille, il y a presque identique pour moins cher

Optically excellent but I have to mention the brilliance of the large grooved sides. This allows me to grab the polarizer and quickly screw it on and remove. With all other brands, I find it very difficult to grip and turn the polarizer to mount and remove.
