82mm CPL Filter, HD Ultra-Thin Copper Frame, 36-Layer Anti-Reflection Green Film, Nano-Xcel Pro Series
SKU: KF01.1990
Love this polarizer so glad I bought it. Believe me when I tell you that you should pack a rubber band with this filter too as sometimes it’s really difficult to take off. The right size ban around the rim of the filter is a great way to get any stuck filter off but this filter is especially tricky because the top layer rotates when you try to unscrew the base layer so your hand just slips around a filter that is wound too tight. Which happens more often than you think. Thanks for coming to my TED talk.

Cumple con la oferta del producto. Es de muy buena calidad. Salvo que debe estar bien ajustado al lente ya que, al girarlo, en ocasiones se suelta del lente. Tengo dedos gruesos y se me ha dificultado el giro.

Easy to use and install. Packaging is very professional. Installs easy and functional as the product stated. Recommend to all, buy it. BUY IT!!

This is a really, really nice CPL filter. It has a very slim design so it doesn't result in any vignetting, even while using may long telephoto lens.
Threads onto my lens easily without issue.
Adjustment of the polarizer is smooth and predictable.
There's no color shift or any other artifacts from the filter. Just crisp images with accurate color.
The filter comes with a nice fabric storage case, along with a microfiber cleaning cloth.
There's also a little instruction card that details how to use the box the filter was packaged in as a photo frame. Kinda kitschy but whatever. I just tossed it.
Great quality though.

Love this polarizer. So many polarizers I've tried cause color tinting at different polarizations. This one doesn't seem to have any of that. Crystal clear image, smooth turning, overall great.

While my particular polarizer did seem to have a blemish that caused it to not work with my camera lens, K&F were very quick to offer support and refund my purchase. I value this empathy for the customer very highly and was completely impressed by K&F in that regard.

Since the filter was positioned as a member of their flagship lens filter line I definitely had already high expectations in the K&F Concept Nano-X PRO CPL filter.
It certainly made its first impression while unboxing it -- it comes in a stylish box and inside that box is an elegant leather filter carry case.
But more important is of course what it delivers in front of a lens. And that is indeed amazing: I tested it on different lenses, a 70-200 mm lens and on a 35mm. Based on physics of a CPL filter in general it is not advised to go wider than 24mm.
I found no distortion problem; reflection and glare get well mitigated; no vignetting or spots, or dark areas detected within the focal lengths mentioned. Also, of course, keeping a certain angle towards the sun will determine the outcome.
That is definitely a high-end filter and I think K&F has made it into the professional market and its expectations.
I was happy with the test results and can recommend this filter, it is a well-worth investment, and my motto is 'better no filter at all than a cheap and bad filter'.

used this for an Iceland trip and was able to capture some phenomenal images when it was on my glass (primarily a Tamron 28-75mm f/2.8 with a Sony a7ii). The ring itself is a little stiff, but that's great for a polarizer - means you have one less thing to worry about when framing your shot in that this won't turn a few degrees on you. In terms of negative impacts to image quality, I can't notice many but I'm not exactly a pixel peeper. For my uses, this fit the bill!

This filter and its packaging exudes quality. But of course, it all comes down to the filter itself, regardless of how nice the packaging and presentation, and this filter didn't disappoint.
I tried it out on my Nikkor 24-85 on a Nikion D800 for a few basic comparison test shots (see my pictures). The polarizer is easy to turn and feels fluid. Dialing in the right spot is pretty easy. I noticed no degrading in the image quality, attesting to its glass and coating quality.
It comes in a really nice case with a wrist strap. The box can even be converted into a picture frame... pretty clever. It also comes with a vacuum packed lens cloth, which I haven't opened yet, so I can't say how nice it is. Overall, it seems like a very high quality filter for their new flagship Nano-X PRO Series.

K&F Concept Nano-X PRO Series Polarizing Filter 67mm
From the packaging to the finished image, everything at the highest level. Quality and workmanship of the filter is top top top. It turns smoothly into the lens thread without cramping. The rotation mechanism has a good resistance and can be adjusted perfectly. The image results are convincing and I could not notice any negative effects. (Color fringes or the like)
Now how do you evaluate the price of such a filter? I think people with photographic experience know what such a high-quality filter costs. I think the price is quite reasonable for the high-quality and very well-made filter.
