K&F Concept 37mm UV/CPL/ND Lens Filter Kit (3 Pieces)-18 Multi-Layer Coatings, UV Filter + Polarizer Filter + Neutral Density Filter (ND4) + Cleaning Cloth+ Filter Pouch for Camera Lens (K-Series)

I bought this to protect my RF 100mm macro. It fits properly, I heard here that in some cases it got stuck to the lens. It was not my case, and I would like to say that you just need to be careful when threading to the lens, since that thread is very fine and you could overlap threads and ruin the lens. However that is in my opinion not a fault of the UV filter, just the way threads are. Thread it carefully and it should go nice and easy, see if it unscrews easily as you advance to make sure you are doing it properly and you will be fine.

I Like the Filters After Using that Images Qulity was very nice and now i dont need to make much color corrections on photoes for sunlight clicked and outdoor photoes

Great price and quality

The Circular polarizer filter is very stiff to rotate to achieve the effect desired. If rotated counter clockwise it unscrews.

Good quality for the price. Definitely a good value.

The CPL filter is probably my go-to especially when shooting interviews. It ry helps clean up those exposed spots on the face. The kit itself is really nice and quality material. The case durable and keeps the filters in place during travel. Love that it also came with the cleaning cloths.If you’re new to filters like me this is definitely a good beginner/intro Kit learn how to use them and which to use in different scenarios. Thanks K&F for a great consumer level product that works!

So far the filters look great , will be testing within the next few days.

Lenses arrived but the ND4 filter was cracked. I reached out to the company to ask for a replacement and they shipped out a whole new set for the trouble. I was impressed with the response speed and their willingness to make things right. The lenses are decent quality as well. I've used the circular polorizing filter to take some great shots of river otters, using the filter to eliminate glare off the water surface. If you don't know the filter is meant to be turned while you look on your screen to find the best angle of rotation for glare reduction since this is variable. While it won't kill it completely, it will reduce glare significantly and improve the picture quality. The UV filter is great quality for the money and I took pics with and without and saw no reduction in quality with the extra glass in front of my lense. I have not used their ND4 lense yet but I did purchase their Nano ND1000 lense to take some long exposure shots and the nano line is even better quality glass and worked perfectly. While I did see a slight color shift I was able to fix in post without much effort. Pretty much par for the course when it come to heavy ND lenses based off my research in the matter. Overall, I feel this is a good buy for the beginner photographer like myself that wants to dabble with lenses and not spend a small fortune. I will say you need to spend a minute cleaning these lenses once you get em since they have some fibers and smudges on them. I would assume this is standard practice at this price point.

Three great quality lens filters in a cool carry case. It not only makes it easier to carry them but protects them too! I am very happy with the optics and the level of multicoating, it just works.

Used these for travel and found them very good quality.Case included is tough and protects the filters.Good price.

Only things is the CPF. Kind of not able to take it off.

Very good value and does the job well

All lens fit wonderfully on Canon M50 15-45mm kit lens, pouch feels premium. I can still fit my lens protect cap and also my lens hood on! The only problem was that it did not come with a cleaning pen as advertised, just a cloth. Contacting the seller was quick and efficient communication which let me know that they replaced the cleaning pen with the cloth (as customers found cloth better to use) but unfortunately Amazon did not update the item listing correctly. Overall very happy with the purchase!
