After years of using screw-in filters and square filter holders for neutral density filters, magnetic filters are a breath of fresh air. They are quick and easy to fit to the front of the lens and easy to adjust. The optical quality of this CPL is very high -- no colour cast or other optical issues -- and I was able to do fine adjustments when shooting at a lake to carefully control the amount of reflection (see picture). I also like the price: very competitive compared to some other magnetic filters that cost as much as a new lens!

This is an innovative design that removes the need for you to swap your protective filter (UV or whatever) on the occasional need for a polarizer. I've tried keeping the outer ring where this fits on top of my normal UV filter. It just snaps on. Of course you should take it off and not meant to be kept there permanently since a reasonably hard bump will unstick it. However, if you're doing landscapes on a tripod, and not walking around this is good.

Optically, its very good. I've no complaints. I am a bit surprised that it seems the sky was bluer without the filter than with. I'll have to do more tests to see. Probably modern digital cameras compensate the colors. It was a Nikon Z7ii.

good product

Pretty happy with this filter. The magnetic aspect makes it a breeze to pop on and off. No cross-threaded filters or fumbling. The CLP works well and does what it is supposed to do. Diminishes glare and intensifies blue skies. A CPL is one of those filters I never go without, especially for landscape photography. The filter is well-made and finely machined.

This has been my go to filter as the magnetic attachment makes it so practical

The K&F Concept 62mm Magnetic Circular Polarizer Lens Filter is well made. Feels like good quality. Looks great on my Sony lens as well. Great product for the money.

This CPL filter is part of their nano k line. Their nano k line is their budget line. This CPL filter works pretty good. There are no image quality issues and easy to install on lens without having issues as well. There is a slight color shift but it's expected with this line being that is the K line. It is not noticeable so most people will not notice unless you're a deep into color correction. The price for this CPL filter is pretty good considering they have a higher end line which is much higher price. It offers you be protection like most CPL filters and there is no issue blocking UV light. I've included a photo from my UV light being flashed directly.

Well constructed, easy installation and simple to use.

Polarized filters are super handy for when there is glare off of a surface like glass or water. Usually, this means taking out thr right filter, screwing it on and then taking your picture. With this filter, it has built in magnets so it just pops on! This makes it super easy to go from off to and back to off in a snap. Adding this to your collection of filters is way worth it!

I’ve been a fan of K&F Filters and accessories for some time now, and have come to appreciate the consistency and quality of the brand. The majority of my lenses live their lives with K&F UV protective filters on their front element.

Like many others, as the caliber of mobile phone imagery and videography have improved to levels of near professional quality, I’ve begun to concentrate more energy into taking advantage of those attributes, not to mention the portability. Both in videography and photography, whether using a full-size camera or a high-end mobile phone, I consider a CPL filter essential. It also has the effect of neutral density.

In hand, the K&F Concepts Magnetic Circular Polarizer Filter System gives the impression of quality. Between its matt 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 attached magnetically, the CPL still rotates freely, as is necessary to adjust its angle; it must be magic.

The only disappointment in the system for me is the lack of usable threads on the front of the CPL; I prefer to use lens shades and would like some means of attaching them. Or to have the option of stacking another filter or step-up ring onto the system. That said, step-up/down rings with appropriate 52mm threading can be attached to the threaded adapter ring, for example a 49mm – 52mm step up ring will allow the use of the 52mm CPL on a 49mm threaded lens. On the other hand, the lens I’ve included in the pictures takes 52mm filters and its built-in lens shade works fine with the 52mm K&F Concept Magnetic System, but the lenses front cap doesn’t. I’ve looked through the K&F Concept Store and they have a number of other magnetic filters, filter sizes and adapter ring combinations in their magnetic eco-system, most of which do include a magnetically attachable front lens cap, including circular polarizers; why they don’t include one with this combination I wouldn’t know, but I think they should. The convenience of the system is negated if in order to protect the font element of my lens I need to unthread the adapter ring in order to place on a lens cap. I didn’t note anywhere in their Amazon store that a compatible magnetic lens cap is being sold separately.

In my view, a complete system, and I’m not referring solely to K&F Concept in this regard, would include magnetically attachable lens caps and lens shades as part of the eco-system. Or if not that, front threads on the attached filter, or corresponding adapter rings, that are the same size as the rear threads of the adapter, allowing for a more versatile system, and one that would accept the users currently owned screw mount filters.

In any event, I have complete confidence in the quality of K&F Concepts filters and their products generally. They are a reliable company that stands behind their product lines. If you’re interested in a magnetic filter system, including this one, I suggest perusing the K&F Concept Amazon Store to see all of the available options. Have fun.
