37mm Circular Polarizers Filter, K&F Concept 37MM Circular Polarizer Filter HD 28 Layer Super Slim Multi-Coated CPL Lens Filter (Nano-X Series)

Your browser does not support HTML5 video.  This is a good quality filter. It works just as I had hoped and is nice for filtering out light reflections. As an example I took some pictures and video of a car while moving the filter around. You can see how it changes what is actually reflected. This is great for car photography, taking pictures of sky, and useful if you are taking pictures of water as well.

great price for a quality filter.

The performance of this CPL is quite good. I am able to achieve the results I expect with it. This CPL has been out in the elements for a few dozen outings thus far without issues. The polarizing effect is strong enough that you are able to dial in the amount of effect you want in your shot.I've used it for car photography by shooting with the CPL at various angles and then stacking the images for the desired effect.I highly recommend this product.

Ths CPL turned out to be great. I was afraid that the green nano-coating could cast a greenish tint on the image. I haven't noticed any annoying green tinting although it does have a slightly warmer and maybe yellowish look. Nothing that can't be controlled with proper white balancing and some minor editing. I find this CPL to be really good for the money.My only issue: my lens cap seems to not fit properly over this filter. I can still use it but it falls off easily. Keep this in mind.EDIT: I'm taking a star from this because taking the filter off is a nightmare. I usea high en IV filter from B+W on my favorite lens and got this K&F cpl for that same lens. Before purchasing i asked and made sure the filter was not only stackable but meant for it and i was told, here on amazon and other sites, that it was totally fine. well, I'd love to have some of those advisors to try andtake off my cpl from that B+W filter. It's like they fused together. Moreover... I had an acciden yesterdayand the cpl got some mild scratches. I'm trying to take it off so i can decide whether to get a new cpl or not. Well, no matter what i try (and I've even tried the ribber band trick K&F has on youtube), its not working

As someone that does a lot of automotive photography, having a polarizer helps a lot to get rid of some of the reflections of the car. Of course, there are numerous polarizers to choose from but I did not want to spend $100+ for a polarizer if a cheaper one could perform just as well.I used it with my Sigma 50mm 1.4 ART lens and I am very impressed with the capability. The circular polarizer is very well made, very sturdy and great at removing reflections off of cars (what I mainly used it for).Overall, if you are looking for a CPL for automotive photography, the K&F Concept does what it is intended to do. And, the best part is the price! It is very inexpensive compared to the other CPLs, such as B+W.

At first glance the filter carrier is well built and also has various holders so much larger or smaller filters. When ever purchasing a filter I’ve always gone outside to check out the polarising effect and didn’t see much as I expected with my eyes, but on camera it looks very beautiful and highly recommend this product, very well built.

This is my first K&F filter and build quality is really good. It has a slim profile and the polarizing feel really smooth.I've used Hoya filters B+W filters below, which are a bit expensive, but provide extraordinary image quality. This K&F filter offers similar picture quality to the Hoya, which is great, at a cheaper price. It also includes a "usable" filter holder that more expensive options don't include in the package.All in all, excellent balance between price and quality.

Moved over to mirrorless camera setup and needed a new filter for it. There case for it is great, I can use it to hold securely any filter not just the one I bought. Images seem sharp and does exactly what a cpl filter should do. Overall pleased with product

I wanted to try out a nd filter for my canon lens, i did like the effects i got in my photos but boy was it a mistake to purchase this for my expensive lens. I read the comments about the filter getting stuck on other peoples lenses and just did not believe it until I went through it myself. You don't even have to screw it tightly for it to get stuck. I barely put any effort screwing it on and it got jammed. Its probably because of the material. Regardless this is an eye opener I'm returning this. Im just going to spend a little more and get a good filter. These cheap ones aren't worth damaging my 3k lens and 4kcamera. If your like me and have an expensive camera just invest in a good filter as it is an investment like your camera.

This is amazing, really cheap and really good, high-quality glass, I accidentally dropped it and it didn't even have a scratch! works very well, and the ring isn't too loose. However, if you tighten it a bit to much,it will be hard to remove.Recommend using a rubber band to remove it in that case,although it is very very good, recommend it 10/10, you won't be disappointed!

This CPL filter had pretty good review in Amazon and that's the reason why I bought it. But I found that the Image Quality is not good enough when compared to my previous Gobe CPL filter. The photos are not sharp enough..I will test it a couple of more times and might return it if I confirm that it is not good enough.. It is only $40/ and you get what you pay for.Update: I returned the filter as I was not happy with the IQ. I will buy Gobe filter instead..

The filter itself seems fine. A bit dark. But, the case it comes in is absurd. It's clearly designed to be a universal (has markers going up to 82 mm), but I purchased for a 40.5 mm., which means the case dwarfs the filters. Its hard heavy plastic, so not something you want to add to your camera bag for no reason. Silly that they didn't include a case that actually fits each filter. [I annotated someone else image to show the size of the case.]

Great build quality and image result. When putting on, twist slowlyuntil is stops, does not need to be forced closed as it can get stuck, this is not a quality problem at all in my eye would buy again.
