This K&F Concept Clip-On 67mm CPL Magnetic Phone Lens Filter Kit is very easy to use and fits over my iPhone camera perfectly. However, it may not work for other phones with different camera configurations. The filter does help significantly reduce harsh reflections, but I’m not very impressed with its ability to deepen and enrich blue skies. It comes in a nice protective case with a microfiber lens wipe as well. Unfortunately, this is not a rotating circular polarizer like the ones they make for DSLR cameras. On the plus side, it does have a magnetic mount, so it’s easy to adjust and swap out with other filters as needed.

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'm using this with a Galaxy S24 Ultra, which has camera lenses that protrude from the back of the phone quite a bit. The clip frame for this microscope lens comes with optional pads you can use to accommodate for a phone like that. The clips will inevitably go over the buttons, but that's really not a big deal to me.Anyways, I included some test shots of various things. First is the texture of a plastic armrest, then closeup shot of outdoor fabric from the same chair. Last is a small ring that my partner was wearing. These photos were not processed or cropped in any way. Depending on your phone camera's lens, you'll likely end up with a little big of vignette unless you crop it or combine with your phone's zoom. You do need to get pretty close to the subject with this and focusing can be a challenge due to the fixed aperture of most (all?) phone cameras. If your phone has different cameras on the back, look up the specs and see if one has a higher aperture, then try that if you're struggling with focus. Plus if you use it with a phone that has an optical zoom telephoto lens, you can increase your total magnification even further.The built-in lights are also really really handy, because you have to get so close to the subject that you wouldn't have much light on it otherwise. Charges easily with USB-C and the ability to lock the frame position and then just clip out the lens to swap in one of their other ones like the 200x is really really handy so you're not needing to reposition all the time.

Just when you thought... who would reinvent the wheel? K&F did it so well! I have the bevy of traditional filters and have always been screwing them on and off, carrying them with me, etc. All the usual ways we all use. That's what caught my eye when I saw "magnetic" and although... eh, seems weird. But I'm always ready for life when it comes to those little things, so I gave these a try. And now I find if I had to screw my filters on it would drive me crazy. This is a MUCH BETTER mousetrap for filter play! I swap out filters more often and use them more than I normally would. The magnets are strong and the filters are what you expect them to be. So far I love these. They just clip on, you screw on the magnetic ring and then the filters clip onto it. Your lens cap goes on top of the filter, so if you don't want the filter, I take it upon myself to take it with the lens cap and set it aside until I need it. If you use or swap out filters a lot, do yourself a favor and get these! I'm about to order a few more sets for my other lenses.

The K&F Concept “Phone Lens Filter Kit, Phone Clip with Magnetic Adapter Ring/Cold Shoe/Locking Knob, Polarizer Filter for iPhone 15 Pro Max 14 13” is a quality filter great for reducing glare. The clip is less user-friendly. I was hoping for something that I could quickly put on my phone and then take off. This clip works, but it is not quick to install.

I recently tried out the 52mm Clip-on ND2-400 Phone Camera Lens Filter by K&F Concept, and it's transformed my phone photography experience. This versatile filter offers a wide range of light reduction options from ND2 to ND400, allowing for creative control over exposure in various lighting conditions.

The clip-on design makes it compatible with a range of smartphones, including the latest iPhone models, ensuring that I can achieve professional-quality results with my mobile photography. Whether I'm capturing landscapes, portraits, or action shots, this filter helps me achieve the perfect balance of light and shadow.

Overall, I highly recommend the 52mm Clip-on ND2-400 Phone Camera Lens Filter to any smartphone photographer looking to elevate their images. It's a compact and convenient accessory that delivers impressive results, making it a must-have for mobile photography enthusiasts.

All in all a very good camera for the price!

I have a lot of K&F Concept surveillance camera optical filters that I regularly use and I have been very satisfied with the quality so I have a good experience with the brand.

The camera uses the CloudEdge app, which is a platform used by many different manufacturers of security cameras. Pairing the camera with the app is made super easy, and viewing recordings or a live feed from a remote location is easy and reliable. You have the option of paying CloudEdge for a monthly cloud plan and having the videos stored on the cloud, but this is not mandatory. The advantage of this service is that if the camera is stolen, you'll have access to the videos it recorded, otherwise you're out of luck because you won't be able to connect to it to see the recordings. You can get a free 7 day trial of the service to test it out.

The video quality is reasonably good for a security camera, though it doesn't compare to the quality of a smartphone. Having the option to remotely pan and tilt is a great feature so you can remotely check on different areas of your property. You can pinch to zoom on the video in the CloudEdge app but be aware this is only digital zoom, the camera doesn't have a physical zoom lens. Technically this is not a PTZ (pan tilt zoom) lens but just a pan/tilt lens.

The camera comes with a solar panel, which is awesome because it means you never have to worry about charging the battery.

Audio quality is comparable with other security cameras I've used, which is to say it's not great but it's adequate. The audio has a little bit of a muffled, underwater sound to it.

A 64GB K&F Concept branded micro SD card is included, which is a nice touch.

The price is reasonable for this good quality, wire-free, solar powered security camera with pan and tilt functionality so I would definitely recommend this.
