well packaged...comes with soft case to protect both the phone clip and the 67mm filter.

The clip is mounted to phone using a screw type mechanism. There's a soft rubber material at the end of the screw to protect from damaging the phone. It was easier to align the phone clip from the camera lens side then gently tighten the screw. Clip stays on phone without issue. The included 67mm filter attach to clip magnetically; also stay on phone without issue.

The clip has a camera hotshoe compatible slot at the top. Good spot to add LED lights.

I got my new K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit today and anxiously opened it to give it a try. My first impression is that this K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit is a well built camera phone accessory.
It is made of metal, aluminum I think, and is solid. It comes in it's own zippered case with foam packing that speaks of quality too. The nice feature about this K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit is the magnetic method to attach the filter. The filter itself magnetically snaps into place with a firm grip. There is no concern that the filter may ever just fall off.
The K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit connects via a thumb screw that tightens onto the camera screen to hold the filter frame secure. This is a bit concerning to me as I would think that if you aren't careful you could over tighten the screw and end up breaking the phone screen.
When I attached the K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit to my Galaxy S23 Ultra, which has 5 camera lenses, it looks like the filter slightly blocks the bottom camera (Telephoto 1). However, as I switched between the camera zooms and I didn't see/notice any actual blockage of the lens. I will keep an eye on this as I use theK&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit more to see if any thing is ever obstructed by the filter.
The filter lense itself also is well made. It has an aluminum outer ring and fits nicely into the frame and the lens is made of glass that is tinted for the CPL effect.
In all, I give the K&F Concept Clip On 67mm CPL Magnetic Phone Lens Filter Kit a thumbs up, but I do worry about over tightening and cracking my phone screen.

This is a nice set that works well with my Tamron lens with a 67mm filter. It screws on easily and provides additional protection at a reasonable price. It comes with a lens cap and tether which is handy. A nice UV filter that does the job well!

I recently bought the 67mm polarizing filter for my Sony A6000 in combination with the SEL16-55G lens and am very happy with my choice overall! ✔️ Improved image quality: The polarizing filter reduces unwanted reflections and enhances colors, which delivers impressive results, especially for landscape shots. ✔️ Robust workmanship: The filter feels solid and high-quality, which suggests a long service life. ✔️ Easy to use: Screwing the filter onto the lens is easy and works smoothly. ❌ Difficult to unscrew: Unfortunately, the filter is difficult to unscrew from the lens, which can be a bit frustrating when changing lenses quickly. Overall, the 67mm polarizing filter largely met my expectations.

This K&F Concept 67mm Variable Fader ND and CPL Lens Filter is a really good, adaptable lens filter that combines two common lens filters into one with a variable adjustment. I was immediately impressed by how smooth the filter was. The adjustment itself is smooth and tight and the actual transition of the image is smooth to match it. The quality seems very good overall and it threaded smoothly onto my lens.

One note, I did not realize ahead of time is that you will need a different lens cap to fit on with the new filter. I have a 67mm lens and ordered the 67mm lens filter. My original lens cap does not fit on the new filter, so I now need a 72mm lens cap to go on this. There is a chart buried in the product description that shows the adapted lens cap size for each filter size but it is essentially a standard size up from whatever filter size you order. These are fairly inexpensive and easy to come by, but it would have been nice to include a corresponding lens cap with the product.

There are many applications where this comes in very handy and can allow you to get unique shots that would be difficult or impossible without this. Some applications would include scenarios like:
- mixed lighting conditions with bright and shadowed areas to balance the exposure;
- removing glare and reflections on reflective surfaces like water;
- landscape photography to reduce glare and improve the appearance of the sky; and
- taking long exposures in brighter conditions without overexposure.

The filter set to minimum does darken the image slightly. Also hoods and other accessories do not fit with this filter, so there are instances where you'll want this off the camera, such as low-light conditions. Still, this is a great all around filter that is worth having in your bag.

Overall I am very happy with the quality and function of this K&F Concept filter and would highly recommend it. Do keep in mind that you'll need a larger lens cap diameter than the size you order, but other than that I think this is a very worthwhile pick.

I recently got the K&F Concept 67mm Black Diffusion Mist 1 4 Effect & Variable ND2-400 (1-9 Stops) ND Lens Filter and it is incredible! This filter has adjustable levels of density, allowing me to get the exact effect I'm looking for. Not only that, but it's multi-coated with 28 layers of Nano-X Series and made with high-grade materials that feel sturdy.

I am very pleased with this 67mm ND filter from K & F Concept. I am using this on a Sony 24mm 1.4 G Master lens (Bonus it will also fit on my 85mm lens). This is great for time lapse photography during the bright afternoons in Florida. Examples of the scenes I've shot are, the summer rains coming through over the water, or of the city scenes at the urban farmers markets, etc., this filter has exceeded my expectations.
I purchased at medium sized backpack from K & F 2 years ago that has been a hearty addition. The backpack has protected my gear on trips to Thailand, Hong Kong, Philippines, and Colombia. So, I figured why not try their other products. I'm looking forward to using these filters for many years to come.
Great buy at a great price.

77mm polarizing filter adapted to a smaller 67mm lens. Fits :)
