This filter is doing its job perfectly. It catchs night light pollution so I could take clear night sky. I've tried it at Josua tree national park to capture Neowise comet, and it worked perfectly.

Construction is very good with rubberized edge ridges for easy installation and removal, especially important for a filter that will only be used for night sky photography. Light transmission is good with no apparent chromatic aberration from edge to edge. The filter doesn't easily attract dust and cleans well with a quality microfiber cloth. While I've only taken a few night test shots, the filter appears to be very effective, especially for sodium vapor light pollution. One more item of note - the filter case is the best I've ever received with a filter of any price!

The filter fits perfectly with my Canon EOS 2000D 58mm lens and allows for effortless attachment and removal. The resulting photos are exactly what I hoped for and the filter works great. As I got into nature and plant photography, I discovered the value of the filter in full sunlight. It helps capture the right density, regulate exposure, improve contrast and minimize glare and reflections. On bright days, this filter has become my favorite accessory. Along with the filter, you also get a lens cap, storage case, lanyard and microfiber lens cleaning cloth, all of which are much appreciated. Overall, this filter set offers great value for money and is a top-notch offering from K&F Concept.

I bought a Canon EOS M100. To protect the lens, I bought this UV filter. As with other reviewers, I can confirm that I don't see any distortions or similar impairments. Installation: The filter simply twists onto the lens (clockwise). Canon lens protectors can still be used. As before, only now the UV filter is inserted into this. The UV filter arrived well packaged. I could use it straight away and didn't have to clean it beforehand.

I screwed the UV filter onto my Canon EOS 650D with ease. Great pictures taken with it. You can see the difference!

I liked everything about the price

This is a very nice high quality ND filter, as expected of K&F Concept. I'm using it with a Canon EOS 5D DSLR, and it is very fun to play with. I haven't used an ND filter like this before so I'm still learning, but you can definitely get some cool effects especially with moving water. The glass is high quality and the picture is sharp and clear. I have a couple of other K&F filters and this is just as nice to use as the others.

Excellent filter for the price... I'm attaching a photo taken with the Canon EOS M50 and 22mm f/2 in daylight... also great for long exposures. However, if you're shooting with extremely bright lenses like f/1.2 or higher, obviously in very bright conditions just 16 layers will do very little
