I've been a fan of K&F filters and accessories for some time now and have come to appreciate the brand's durability and quality. Most of my lenses live their lives with K&F UV protection filters on the front. Like many others, I've started to focus more energy on taking advantage of these features, not to mention portability, as the quality of mobile phone images and videos has improved to near-professional quality levels. In both videography and photography, whether with a full-size camera or a high-end mobile phone, I find a CPL filter indispensable. It also has the effect of neutral density. In the hand, the K&F Concepts Magnetic Circular Polarizing Filter System gives the impression of quality. Between the matte black finish, the 52mm magnetic adapter ring, and the reflection of the rich multi-coatings, it's an impressive filter. Interestingly, despite the fact that the adapter and filter are magnetically attached, the CPL still rotates freely as needed to adjust the angle. That must be magic. The only disappointment with the system for me is the lack of usable threads on the front of the CPL. I prefer lens hoods and would love a way to attach them. Or to have the option to mount another filter or step-up ring onto the system. However, step-up/down rings with appropriate 52mm thread can be attached to the threaded adapter ring. For example, a 49mm — 52mm step-down ring allows the 52mm CPL to be used on a 49mm threaded lens. On the other hand, the lens I showed in the pictures takes 52mm filters and its built-in sunshade fits well with the 52mm K&F Concept Magnetic System, but the lens' front cap does not. I checked the K&F Concept store and they have a number of other magnetic filters, filter sizes and adapter ring combinations in their magnetic ecosystem, most of which include a magnetically attachable front lens cap, including circular polarizers; why they don't include one with that combination I wouldn't know, but I think they should. The convenience of the system is negated if, to protect the font of my lens, I have to twist out the adapter ring to put it on a lens cap. I didn't notice anywhere in their Amazon store that a compatible magnetic lens cap is sold separately. In my view, a complete system, and I'm not just referring to K&F Concept in this regard, would include magnetically attachable lens caps and lens hoods as part of the ecosystem. Or failing that, the front threads on the attached filter or the corresponding adapter rings that are the same size as the rear threads on the adapter, allowing for a more versatile system and one that would accommodate the screw-on filters currently used by users. In any case, I have full confidence in the quality of K&F Concepts filters and their products in general. They are a reliable company that stands behind their product lines. If you are interested in any magnetic filtration system, including this one, I suggest checking out the K&F Concept Amazon store for all the available options. Enjoy.

Do not reduce too much light entering the housing. I only use it as a protection for the front lens

We bought this camera for security at our apartment. This has been the best buy we have made. I can check my front door when someone comes on our porch plus I can keep an eye on my car. The picture quality has been great day and night. Plus it's solar-powered so no worries about the battery. And the memory cards make it easy to keep events for later viewing. I would say buy this one for easy set up to the phone and for easy to put up. Worth the money!

I bought the camera to monitor the outside area in front of my front door and am delighted with the quality of the camera.
The installation went smoothly and the area can now be easily viewed via the app. The camera is charged via the supplied solar panel, so no power connection is required! Perfect. I can recommend the camera unreservedly.

I put this camera on the front door. It's very easy install and setup. Video quality looks great. Love that it’s wireless and no longer have a 9 foot cable hanging on my wall. App is pretty intuitive.

I set up this camera to watch my front door but also wanted to be able to keep an eye on my backyard when the dogs go out so needed one that would pan. I mounted it on a beam of the roof to get a good view so the solar panel is an awesome addition to avoid having to remove the camera to charge it. It's been about a week and still 100% battery so the panel is working as expected! This was my first piece of equipment that came with a solar panel so I was a bit intimidated but it was much easier to setup then expected.

I took it to my kitchen and living room and tried the quality before I placed it front of the door. It’s capturing not only my front door but my driveway also.
Couldn’t be happier!
