Very good surface quality and excellent photo quality. It corresponds to the PL filter, not like others that they only darken the image

Very good

The product looks very professional and works very well

This is a great filter set that includes both a UV and CPL filter, but also a nice case to protect the filters when they are not off the camera. I have been using it for over a month and have found it to be of high quality and perfect for my needs. I highly recommend it for the value and overall quality.

I am very impressed with these filters! Not only do they look high quality, but they feel high quality as well. The weather conditions near me haven't really allowed me to get some good nature shots with this set yet, but the test shots I took near my house look great. The only thing worth noting is that I keep accidentally partially unscrewing the filters when adjusting the CPL - I'm sure it will just take some getting used to.

I am very pleased with the lens cap and rear cover included - they make for slim storage, and I appreciate that since I often like to travel with a small camera bag.

Overall, I'm very pleased with this set and would definitely recommend it.

These filters are available in many sizes. The 58mm fits perfectly on my Nikon 50mm 1.4 lens. Like all circular polarizing lenses, it provides varying degrees of filtration once mounted. The mount is thin, so this takes some getting used to, but the glass is good quality and the results are good. In certain types of light, it enriches the color. It's especially good for clouds and water. (If you've never used a filter like this before, note that it reduces the amount of light reaching your sensor, especially when set to maximum. Hold on to your camera.

The set comes in a nice storage box with a drawstring cloth bag 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 may like to use the front one when taking photos. I don't like it myself. It is very protective, but I find it too hard to mess with when I want to achieve a lighting effect. My normal removable lens cap works fine on the front of the filters.

Very nice filters! Arrived quickly in good condition. I will be using them a lot this year for winter landscapes.

"Every lens should be equipped with a high-quality UV filter for protection. This 52mm Nano-X circular polarizer filter and MC UV protection filter kit from K & F Concept has such a filter. The kit also includes a circular polarizer filter and 2 high-quality lens caps. The 52mm UV filter has found its permanent place in my Canon EF-M 55-200mm STM lens with image stabilization, and the circular polarizing filter will serve as a welcome extra for several other lenses so I don't have to play "switch filters" between them. The included lens caps are very nice, but I find that it sometimes takes a bit too long to remove them, and I prefer the clip-on style that can be removed instantly.
Both filters improve image quality by removing glare and haze, respectively."

I didn't have much time with the filters. I usually shoot several times a month, but this time of year I have limited time. I had planned to use them on a hiking trip that was cancelled at the last minute. I took some test shots and checked the lenses for flaws and found no problems.

Instead of the normal hard shell filters that are included, this comes with a screw cap for each end and a soft carrying case for extra protection. In cases like this, I need more than the pinch lens cap. This screw cap protects the filters. However, removing the cap takes a few seconds longer.

The only problem I've encountered so far is that after tightening the filter to the lens, I've only been able to remove it with a lens filter wrench. The gripping surface on the immovable parts is just not enough to loosen it.

I like the filter set and plan to buy more K&F filters for my other camera lenses, and I recommend their products. I will update this add once I have had a chance to spend a little more time with the lens filter.

"I have been using K&F Concept filters for several months and have been very pleased with their quality. This set of a UV filter, circular polarizer and two lens caps is excellent quality and very reasonably priced. As far as optical quality goes, I can't find anything wrong with 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 lightweight. They screw on fairly smoothly, but are not quite as smooth as the heavier brass rings you get on more expensive filters. Brass is naturally a less "sticky" metal, but these aluminum frames work flawlessly, mainly because they have sections of milled grooves on each side that give your fingers a great grip when screwing the filters on and off. I usually rub a little finger grease over the threads every now and then, just to have a little lubrication.

The screw-on lens caps are beautifully made and provide excellent protection, but they will not replace my standard snap-on plastic lens cap for everyday photography use, as I find that screwing a lens cap on and off is too time consuming and cumbersome. Of course, the polarizer and UV filter can be used with any standard snap-on lens cap - you don't have to use the screw-on lens caps.

These filters come beautifully packaged in a foil-stamped, hinged cardboard gift box. Included is a K&F branded microfiber drawstring bag. They would make a great gift for a photographer, provided you know what size filter they use for their lenses.

These are excellent quality filters and well worth the price, so I highly recommend them."
