82mm CPL Filter Circular Polarizer Filter with Lens Cap Optical Glass Ultra Slim 18 Multi-Layer for Camera Lens Nano-Klear

Really nice lens filter. Appears to be of really good quality. No issues with it. Screws on well to my third party Fuji lens!

Nice CPl kit. I love that it has it's own lens cap. It's always frustrated me to have to remove the filter to put a cap on to put my camera away.

Without the CPL the glare on the water prevents you from seeing beneath the surface. With the CPL the glare is cut dramatically and you can see into the water.

Just be mindful that your exposure will change and surrounding rocks may appear brighter. Adjust accordingly.

Circular polarizer is essential for my outdoor photos. It makes skies look great and calms the glare on water. It gives the wow factor to photos. This filter is quality glass and works well. Recommended.

I own a dozen or so filters from various manufacturers for my cameras. We all know that when you're looking for a filter, you will see offerings that run the gamut on pricing, and sometimes it's hard to tell the difference between an inexpensive product and one that costs more. The moment I received this filter, I knew it was special. Let's start with the packaging. Instead of being shipped in just a dinky box or plastic bag, this has a sturdy cardboard box with a metallic sheen. The outside is also completely printed with QR codes for info, specifications, etc. On the inside, you get a sturdy, transparent storage case that snaps close. Inside is the filter with a LENS CAP attached, as well as an orange lanyard. As a bonus, you will get a sealed cleaning cloth. I don't think I've ever purchased a filter that came with a cap retention lanyard and a lens cap before. I am using this for my Fuji X100V, and of course, it fits perfectly. I can use the included lens cap with any filter I decide to use. The only con I've found is that once you get this on and rotate clockwise a few times to get the right CPL effect, the threads are really tight. The threads are also so short that it's hard to get a grip on just that area to get them off. I had difficulty removing the filter from my camera and had to resort to a filter wrench. However, this is not unique to just this filter. All filters could have this problem with removal.

I am not a professional photographer but I dabble and every once in a while, I am able to capture a great picture! I don't know as much about glass as a professional, but I do know that a polarizing lens is a very good option to have on a sunny day. I live in Hawai'i so I have opportunities to take vivid photos of blue skies and oceans. With this polarizer, I notice my blues are more vivid and the oceans have a richer color.
I also take a lot of photos of forests and birds. It's a hit and miss with this type of photography because of the lower light that is typically found in a forest.
This is a really good filter kit- it comes with a lens cap and a cleaning cloth. I am very happy with the package and the clarity of the glass.

This is a good quality circular polarizer. I find that K&F concept filters are generally high quality and this one is no exception.

The build quality is great and the circular polarizer helps shine and reflection to be controlled by rotating the filter. Probably the only small nitpick I have is, I wish there was some physical indicator to show the position of the polarizer, as I tend to accidentally rotate the polarizer while filming.

I enjoy K&F products for the most part and this filter 'set' is no exception.

At 52mm, it's nice and compact. You get a filter, a filter cap, a strap, and a case and cleaning cloth.
The CPL operated very smoothly with no slop, and the filter improved every image I took with it.

Can't go wrong with this filter. It's a keeper.

This works as expected. I did accidentally over-tighten it and had a slight panic that it would be permanently attached to my lens, but did manage to remove it.

Once secure, the front polarizer does smoothly spin to achieve the desired effect at different angles. And it's great to have an extra lens cap with a strap to keep it from being lost.

The filter seems to be of high quality and hopefully will resist scratches.

The CP filter is shipped in a nice plastic case with a lens cap and keeper. While I keep unused filters in a pouch, the cap comes in handy. I like to keep the cap on as an extra safety precaution. K&F also provides a microfiber cloth in the package.
The first thing I noticed was that the filter is thin and light weight. Visually, the threads appeared clean without any obvious imprefections. It threaded smoothly on to my 49 mm FujiFilm adaptor. Once in place, rotation of the polarizer was smooth with what I believe is a bit higher force than I would have liked. However, I find this preferable to a looser ring. Removal of the filter after use, as expected, was a bit more difficult, requiring a bit of force to start loosening it.
I drove to the coast on a sunny day and took a number of frames at various polarizer strength. When I got home I carefully inspected each photo and then compared them side by side. I may not be a professional but I am extremely critical of my work but could not find any unexpected changes in sharpness or color shifts.
In summary, nice filter at a great price.

K&F Concept 52mm Circular Polarizer Filter with Lens Cap Cleaning Cloth Is well made and easy to use. Feels very durable but light weight. It looks good on my camera set up. It’s a great product for the money.
