I was in need of a 82 MM PL filter, I wanted some ND filters so when I saw both at a lower price than the PL alone for the name brand I usually buy I was interested. As someone who spent years selling photo equipment of the pro level to pros I want quality. using with two high quality lenses the Nikon 105 1.4 and Nikon 80-400.
Starting with the packaging the box was first rate, not just a cheap white box. The filters came with a case and I was expecting a wallet style, nice but inexpensive and I was please to see a high quality plastic case that provides better protection to the filters. Best designed case of it type I have ever seen, Thin design but thick strong plastic and with a unique rubber grip bonded in to allow filters of any smaller size to be securely held in place.
While the packaging an case are important the real deal is the product itself . When I opened them I didn't immediately identify the PL as it was the same thickness as the ND filters. Most PL are thicker because of the rotating nature of the filter which can be a problem with WA lenses. Thin often equal flimsy but not in this instance the metal rings are of high strength , the filter rotates smoothly and are of good optical quality.
A problem often encounter with PL filters is difficulty removing the filter, especially so with thin filters as pressure to the sides of the filter in removal will cause a filter to be temporaryly out of round and bind. With standard filters you apply pressure with the palm to remove the filter but that is not possible with a PL due to it's rotation. The thinness of the PL makes it difficult to just apply pressure to the sides and they have very thoughtfully made the two rings slightly different, The outer ring , the one you rerun to vary the effect of the PL is smooth, the inner ring has machined finish with narrow grooves that you can easily turn with a fingernail, a great solution . Of course part of easy removal is not to torque it down, it doesn't need to be tight.
Dont frequently review products but his is one I strongly recommend, especially at the value pricing.

I’ll start this review with a couple of points: I was already familiar with K&F Concept, as I have several of their lens adapters (available here and elsewhere) to use vintage lenses on modern digital cameras. So, I had an expectation of quality from them. Second, I’m pretty much a filter snob. I use a UV filter on all of my lenses as a combination image improvement step and a protective measure.Those things being said, there are three basic filters that photographers should carry: UV/protective, neutral density, and circular polarizer. It’s convenient if more than one of your lenses use the same filter size, because you can just swap between lenses and sometimes stack them. The 55mm size I got works on two families of the vintage lenses I shoot with, and I had been lazy about getting the ND and polarizer to use with them, so this was a way to solve more than one problem. (This kit is available to fit a wide range of filter thread size).I mentioned that I’m a filter snob. If you’re putting an extra glass surface between you and your subject, you don’t want it to reduce your image quality. For this reason, I’ve always used multilayer antireflective-coated filters. On first inspection, the K&F Concept obviously has a high quality coating. They are labeled “HMC,” which is a designation used by one of the major filter companies. It may be that that company makes these for K&F; if so, that validates the quality for sure. Looking through them, they are optically excellent. The filter rim is made with two knurled gripping areas to make it easy to install and remove. (These may interfere with installing some old-school lens caps that fit down over the barrel of the lens rather than clipping on) The polarizer rotates smoothly, and the ND4 is correct for a two-stop light reduction. The included case makes it easy to have the filters ready in your camera kit.I like lens pens. Having a clean lens brush handy is a necessity if you shoot in the real world. But the cleaning tip is kind of amazing: It’s like having a microfiber magic wand to safely remove smudges from your optical surfaces.So, overall I think this is a really nice kit and a great value. You can buy lesser filters for more money for sure. Consider the lens pen a surprise gift.

Been using same filter in various thread sizes for multiple lenses since Feb, 2021. Good threads. Easy to attach. Suggest you go easy when attaching any screw-on filter. Take it slow to keep from having problems attaching. Have taken some excellent, dramatic sunrise and other landscape shots. Couldn’t be happier. Will update if I experience any issues in the future.
