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.

Bought for videographic use, a must if you shoot in V-log. The magnetic anchoring system is excellent if the filter is placed properly: to place it, it is necessary to fit it in its notch; to remove it, it is enough to unhook it from the magnetic ring. In any case, it is a very quick operation. And there's no need to remove the protection filter either (it's true that I use completely neutral Sigma filters, without UV protection). It can even be used with the butterfly-type hood of the Lumix 20-60 on my Lumix S5. The handling becomes a bit more difficult, but you gain in comfort when attaching and removing the filter (for example, in transit from a bright exterior to an interior).
There are no significant aberrations, which is surprising for an inexpensive variable ND filter. Obviously this is influenced by the ND2 to ND32 scale, which is very short for this type of filter. Highly recommended

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!

This filter has been fitted to a Lumix 14-140mm M 4/3 lens and chosen to protect the lens. After practicing with and without a mount for comparison and in different shooting situations, I have not noticed any impact on the base quality of my lens. I am delighted with this purchase at a very reasonable price.

This is a very nice, high quality filter that fits my Lumix FZ80 lens perfectly.

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.

bought the adapter specifically for the Panasonic Lumix G 70. Processing and fitting accuracy are not objectionable. A MInolta lens with 400 mm works great without it shaking. My recommendation. Value for money. I think a much higher quality can't beat it.

The filters fit my Panasonic camera perfectly. They make a very well made and durable impression. I am sure that with careful use and proper care they will serve me well and for a long time.
I think this filter set is a good buy and value for money.
