This is mostly just a screw-on UV filter. I think it will work with the other magnetic filter accessories K&F has on the market. I love K&F filters. They are high quality and hold up well. In the event that they break, you won't have lost hundreds of dollars.

This MC UV Lens Filter has been a great addition to my gear. I already had a CPL filter from K&F and it is around the same size. The build quality is good. It's super slim, feels sturdy and reliable, and no vignetting from what I saw.

The coatings on this filter reduce reflections and ghosting. I tried sunny and cloudy conditions and the filter worked great with both. It also works as a protector for my main lens. As a physical barrier against dust, dirt, scratches, and accidental bumps, it gives peace of mind.

Finally, it does include a lens cap and cleaning cloth which are nice. The cap fits securely and the cleaning cloth is just your standard microfiber. I would say this filter is a great value for the price you pay.

Literally a complete cleaning kit to get dust off, and keep dust off. Cleaning cloth to clean in the first place, and a lens cap that fits snugly but easily removable with a quick pinch... and a mini-lanyard to avoid losing the cap too!

And a fine basic UV filter that minimally impacts your main filter/camera yet protect them all the same.

All for an affordable price. I find no faults in this kit.

Just got back from vacation where I used this cp a lot as we were on the beach and near water all the time. I had previously received another K&F UV/protective filter and was impressed with the quality. So I decided to buy this CP filter before our trip as well. It arrived just in time and exactly like another one I have - it's definitely good value for the quality you get. I usually buy on the used photo supplies market and quality CP filters of this size (B+W etc.) sometimes cost more unless you are lucky enough to get one new in this price range. This filter appears to be very well made, good quality glass and coating, and I didn't notice any artifacts when pixel-peeping on my Sony 7R III with Tamron 28-75mm f2.8 lens with this filter. Definitely recommend checking out this CPL if you're in the market.

Hello,
It's a very good quality ratio for this K&F magnetic filter.
I recommend it.

really like that the filter is unlike any other filter on the market (at least to my knowledge). Haven't tried it during the day but at night when I want to change the shot it's fantastic.

Magnetic Filter Attachment, quick and easy to attach or remove from the camera lens.
THe 1/4 Black Mist filter is fantastic and definitely one of my favorites. The Filter comes with 3 items

1) The Filter Ring that threads on to the lens end
2) The Magnetic filter
3) Magnetic Filter Lens Cap.

Common Question(s):
Can you use the canon lens cap with the Magnetic ring installed (YES)
Can you use the Canon lens cap with the magnetic Filter in place (YES)
Can you use the Lens Cap with the magnetic base without the filter magnetically attached (YES)

Overall, really good quality lens and it is a breeze to install. The Magnetism is strong and the lens cap does not fall off nor does the filter. It has just the right amount of magnetism to keep everything in place.
Very Good Lens and Concept for mounting it to the camera.

I ordered this filter and wasn't sure what to expect as it was cheaper than most brand on the market, I have to say I was very pleasantly surprised!The filter is very solid with a full metal construction. The outer ring spins smoothly and feels solid when adjusting on camera. The images remain very sharp and I'm impressed there was no vignetting like some other ND filters create. I also really appreciated the hard carrying case that it was delivered in as I can carry it with me on shoots without fear of it being damaged.I would definitely recommend to anyone needing a variable ND!
