This filter was purchased for a 12~60mm Panasonic lens mounted on an Olympus OM-D E-M5 MKII. It was difficult to screw on because the first thread was difficult to engage properly despite handling the notches milled on the ring. Thinking it had it fitted, it was unpacked when I took the sun visor off. It is therefore important to check that it is tight and fully screwed. Otherwise nothing to complain about, it protects the lens and filters the light

I own a Panasonic Lumix G85 camera that came with a 12-60mm F3.5-5.6 lens. I really like both the camera and the lens — they're compact and the lens is excellent. Since I occasionally shoot outdoor shots and videos, I ordered the K&F Concept UV filter for those situations and to protect my lens. The filter arrived quickly and out of the box I received the UV filter, a lens cap and a lanyard. Installing it on my camera's lens was very easy and I can already see an improvement in my photos and videos. Overall, I think this is a must-have accessory for the G85 with the kit lens and I highly recommend it.

got a cage for my new GoPro 12 that allows for traditional 52mm camera filters. Usually you have to get the funky square filters for the action cameras, so it's pretty cool to be able to use filters I already own. But I didn't have a good UV filter that wasn't already used on my regular camera lenses, so I got this filter and it works well, and I appreciate the inclusion of a lens cap. The only negative thing about this filter when used on a GoPro cage is that I get a little vignetting when using the camera on the widest setting, "Hyperview." I rarely use Hyperview, so no big deal, but it's worth noting that this thin filter may not be thin enough if you're using it on a super wide angle lens. Other than my minor issue, which probably only occurs when used with a GoPro, I can't find any other faults. If nothing else, I've added another layer of security to my expensive action cam.

It's $35 kit is quite affordable and well priced. It may not satisfy the most professional photographer or videographer, but it will make most hobbyists and semi-professional people quite happy.

I hope the photos are helpful at illustrating what each lens offers. It comes all in a protective case so that you can carry them all with you. The lens fit as expected. they're costing about $12 each including the case and the brush. That's an amazing deal!

One reviewer said that the nd4 filter is not really nd4. Frankly, I'm not sure if he is right or wrong. But since I don't have any ND filters, I'm pretty happy with this one.

For my Panasonic Lumix G lenses, I needed two "protective filters" so that rain and fingerprints can't damage the front lenses. There are different opinions on the net about the effect of UV filters, so I don't want to say anything more about it, but there is a blue-tinted coating on the K&F Concept Pro UV filter, the delivery condition is perfect and the packaging is (especially in view of the the price) can almost be described as luxurious. A first check does not reveal any adverse effects on the image quality, and the slim design means there are no shadows on the 12mm lens. Lens caps continue to fit securely, and the lens hood also fits the lens either way. I see the handy "teeth" on the outer edge of the frame as a big advantage - finally someone has thought along! Especially with the "slim" filters, it is sometimes rather tedious to get them off again after they have been screwed "safely". There are even tools that make this removal possible in the first place. But that's a thing of the past here, with this practical ribbing on the edge it's no longer a problem. At that price you can also have one or two of these filters with you in your camera bag and when the mud has splashed you can quickly put a clean one on - just perfect!

I used it on my Panasonic 45-150 lens, which is the lens I use most outdoors. I misunderstood when ordering that the UV lens is also half of the polarizer, but it works well. The UV filter fits easily and smoothly into the lens, the polarizer attachment filter fits well and works well at an angle to reflective surfaces. The images I took with this using my Panasonic GX85 came out well with no optical aberrations. There are better quality filters, but they cost much more - this set is the perfect combination of price, quality and optical quality. I am very happy with it.

the lens cap fits very well on the object of my Panasonic Limus camera (52 mm). The delivery was prompt. Item and delivery were perfect. Since a 2nd cover is part of it, you also have a reserve. I can only recommend.

Works very well, I only recommend buying an additional lens hood because if there is backlight in the picture, it looks purple in the picture. Nevertheless, I am very satisfied, it does what it is supposed to do, I can't complain
