Great product with a great price. Better than expected

All I NEED to say about these is that I've removed the Hoya and B+W filters from my better lenses, and replaced them with K&F filters. I'm going to add that this filter "kit" is so well built and thought out, with the included METAL caps front AND back when not in use, are so nice that I've now bought several and will look to K&F for my filters BEFORE looking to what I used to consider my "go-to's" in the past. I love these things. Recommended!!!

I'm very impressed with these filters! Not only do they look high-quality, but they feel high-quality too. The weather conditions near me haven't really allowed for me to go out and get some good nature shots with this set yet, but the test shots I've taken near my home have come out looking great. The only thing worth noting is that I keep accidentally partially unscrewing the filters when I go to adjust the CPL - I'm sure it will just take some getting used to. I'm really pleased with the inclusion of the lens cap and rear cover - it makes for slim storage, and I appreciate that as I often like to travel with a small camera bag. Overall, I'm really happy with this set, and I would definitely recommend it.

These filters are available in many sizes. The 58 mm fits perfectly on my Nikon 50mm 1.4 lens. Like all circular polarizing lenses, once mounted, it turns to provide different levels of filtration. The mount is thin, so this takes a little getting used to, but the glass is fine quality and the results are nice. In certain kinds of light, it enriches color. It's especially good for clouds and water. (If you haven't used the kind of filter before, be aware that it does cut down the amount of light reaching your sensor, especially when turned to maximum. Steady your camera. The set comes in a nice storage box with a drawstring fabric pouch and metal caps for the front and back of the filter unit. The metal caps protect the glass from dust and scratches during transport and storage. Some might like to use the front one while shooting. I don't like it myself. It's very protective, but it's too hard for me to fiddle with when I want to grab a light effect. My regular snap-off lens cap works fine on the front of the filters. Very nice filters! Arrived quickly in fine shape. I'll use them a lot for winter landscapes this year.

haven't had much time with the filters. Normally I'm out shooting stuff several times a month but this time a year I have limited time. I had planned to use them on an hiking trip that got cancelled last minute. I did some test shots and checked the lenses for defects and didn't find any issues. Instead of the normal hard case lens filters might come with, this one comes with a screw on cap for each end and a soft carrying case for extra protection. For those times I need more than the pinch style lens cap this screw on cap will help protect the filters. But it will take a few seconds longer to remove the cap. Only issue I've found so far is that the after tightening down the filter to the lens I was only able to remove the filter with a lens filter wrench. There's just not enough grip surface on the non-moving parts to twist it loose. I like the filter set and plan on purchasing more of the K&F Filters for my other camera lenses and I recommend their products. I will update this add once I've had a chance to get some more time with the lens filter.

Very nice filters

Every lens should have a good quality UV filter on it for protection. This K&F Concept 52mm Nano-X Circular Polarizers Filter & MC UV Protection Filter Kit has such a filter. The kit also comes with a circular polarizing filter and 2 high quality lens caps. The 52 mm UV filter has found a permanent home on my Canon EF-M 55-200mm Image Stabilization STM Lens and the Circular Polarizer filter will serve as a welcome extra for several other lenses so I don't have to play "Switch the Filter" among them. The lens caps included are very nice, but I find they take just a bit too long to remove at times, and I prefer the clip on style which can be removed instantly. Both filters improve image quality by removing glare and haze respectively.

As a novice for whom photography is a hobby, I hate to spend hundreds of dollars on filters. However, I do want ones that will detract from my photos. Thus, I am becoming a huge fan of K&F Concept Filters. They are reasonably priced, seem to be of high quality, and do what I need to be done. "K&F Concept 82mm Nano-X Circular Polarizers Filter & MC UV Protection Filter Kit (2 pcs)" was exactly what I needed for my new wide-angle lens and that requires an 82mm filter. The UV filter will protect the sensor and does not seem to impact the sharp photos my lens produces. The circular polarizing filter did not produce dark corners, even at the 16mm setting. Further, when I used the 35mm setting but zoomed in using my camera's various features, there was no dark "X" or distortion. I'm sold!

have been using K&F Concept filters for several months and I have been very happy with their quality. This set of a UV filter, circular polarizer, and two lens caps is excellent quality and is very reasonably priced. In terms of optical quality, I can't fault these. They are top-notch, and easily comparable in quality to Tiffen filters. The filter frames are made of aluminum alloy, which is strong and light; they screw on pretty smoothly but aren't quite as smooth as the heavier brass rings that you get with more expensive filters. Brass is a naturally less "sticky" metal but these aluminum frames work just fine, especially because they have sections with machined grooves on each side that provide excellent grip for your fingers to grab on to when screwing and unscrewing the filters. I usually rub a bit of finger grease along the threads every now and then just to provide a light bit of lubrication. The screw-on lens caps are beautifully machined and provide excellent protection, but they won't be replacing my standard snap-on plastic lens cap for everyday use when I'm out shooting because I find that having to screw and unscrew a lens cap is too time consuming and fiddly. The polarizer filter and UV filter can, of course, be used with any standard snap-on lens cap - you don't have to use the screw-on ones. These filters come beautifully presented in a foil-embossed flip-open cardboard presentation box, with a K&F branded microfiber drawstring bag included. They would make a great gift for a photographer, assuming you know what size filters they use on their lenses. These are excellent quality filters and are well worth the price, so I highly recommend them.

use this for car photography on my Sigma 30mm f 1.4 and it works perfectly to reduce reflections and glare
