I have other K+F filters for other lenses and they have been exceptional. I ordered this duo for the Sigma APS-C 18-50mm F2.8 zoom I use on my Sony A6000. When I stack both filters together, there are severe black corners. When I zoom from 18 mm to 19.5 mm, they are gone. If I use one filter at a time, no problem. So I decided to leave the polarizer on for the summer and reinstall the UV in the fall. Unless I plan to shoot 20-50mm on a given day. These filter rims are so thin that I don't think there is anything on the market that could improve this situation. I have put K&F on other lenses with no problems. Must be just this Sigma lens design.

Very easy to use, attach and remove, improves image quality in the right environment

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

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."
