This press-on filter kit is a practical way to add real exposure control to a phone without turning it into a bulky rig. The mount snaps on securely and sits flatter than most clip systems I’ve tried, so it doesn’t feel like it’s hanging off the phone. Once attached, the 58mm threads feel solid and let the ND filter spin smoothly without wobble. The ND2–32 range is flexible enough for bright outdoor shooting, helping keep shutter speeds and highlights under control when filming or taking long exposures.The lightweight build makes a difference for handheld use. At under 20 grams, it doesn’t pull the phone forward or feel awkward during longer sessions. The silicone padding grips well and hasn’t scratched my case. The included storage case and strap are thoughtful extras, especially if you’re tossing this into a small camera bag or pocket between shoots.At $25.99, it’s a good value compared to buying separate adapters and filters. Compatibility is broad across recent standard and Pro iPhone models (except the 17 Pro/Pro Max), which makes it easy to reuse if you upgrade phones within that range. The only improvement I’d suggest is clearer markings on the ND ring for quicker adjustment in low light. Overall, it’s a compact, effective kit for anyone wanting more creative control from a phone camera.

I love this lens filter! I now keep this in my purse because it works great for things that we have done during the holidays. The picture that I attached is with using it. It's super clear! No glare or anything! It fits the phone ok, just have to be careful to not be rough with it because it will fall off. It's just attached by a clamp so it's not sturdy sturdy.

I got this really just to experiment with what my iPhone 17 camera could do. The kit you get is very nice. A good case, a microfiber cloth, the clip, and the lens. The lens itself is technically lightweight, but has enough weight to it to show it’s quality.The clip was easy to get on my phone and held tight. It does end up covering part of your phone screen, but that’s ok when you’re using this because you just have the camera viewfinder which you can still see most of.Once screwed into the clip, you can turn the filter to adjust the exposure. There are marks on the rim that show you which ND level you’re at. It’s continuous, but there are 5 marked stops. It’s a litle awkward and fiddly to turn the filter and hold your phone, but it’s doable. I ended up moving the clip a bit when I was turning the lens.It worked as advertised to adjust the exposure in my photos without affecting the color accuracy. It’s definitely more sublte than I thought it would be, but pro-sumer photographers are likely looking for that level of fine tuning.I’ll continue to experiment with this when I need to control the brightness or exposure of the photos I’m taking.

This ND2-32 filter is a variable neutral density filter with 5 stops of light reduction (from ND2 to ND32), it’s good for controlling exposure in bright conditions for effects like long exposures (waterfalls, light trails) or wider apertures. It fits my phone perfectly and is easy to put on and take off. It comes with a very nice case and a microfiber cleaning cloth. I’m impressed with the quality of this.

I really do like this K&F Concept variable ND filter with clip for my iPhone. The 58mm filter diameter is the perfect size to use for all three camera lenses without being burdensome. The quality of the K&F filter glass glare reduction is spot on with no weird spots or color shifts. The filter ring is metal and is easy to dial in the filter you need. The clamp is unexpectedly nice too it’s more of a parallel mounted clip (for a lack of a better description). The clip opens wide enough to allow for a phone case, and the retention holds firm all the way around the top or sides, even along the radius corner of the screen edge. The clip is probably the best functioning clip that I have ever experienced using.

I am really impressed with the quality of the lens and kit. It took a bit to ship so I was skeptical of how this was going to go. But the ease of putting it together and applying it to the phone and removing it is really simple. It fits well on my iPhone, but I don’t think it would work for a super thick otterbox case for example. Functionality is arguable depending on what you are using it for but it’s an interesting piece and cool for people who enjoy photography and are just starting out. I wish the kit came with multiple lenses. The lens is really good quality and thick glass. The case it came with was a nice bonus but it stunk of plastic/ chemicals. I do feel like price is a little steep for just one phone lens but the quality is there all around.

It was well-made, just like a K&F product. I was able to use the filter body without problems, but I couldn't use it because the protrusion of the filter clip collided with the gimbal. I hope you can devise a way to set filters for smartphones without filter clips.
