52mm Magnetic MCUV Filter,HD Waterproof Scratch-Resistant Anti-Reflection Green Film with Magnetic Metal Cover Nano-Xcel series

Super practical, easy to use, no regrets, great.

Nicely packaged, comes in hard case. Fair warning, you see the cap and attached is the filter. What you can't see is nothing on the other side of the filter so you might touch it taking it out. But it's cool. Threaded perfectly. Both feel solid. Strong magnet. Definitely buying more magnetic filter.

This product suits me completely and is as described. Product delivered within the allotted time.

The filter is very easy to screw in, the magnetic cover holds even when the camera is carried vertically. I like it much better than the original plastic caps.

I looked at a lot of different magnetic filter systems, but ultimately decided on the K&F filters. It was a great decision. I would have purchased from their new Pro lineup, but they weren't available at the time (at least in magnetic form).

I keep one of these UV filters on each of my lenses permanently to protect them, so I attach them via the threads. It then becomes the magnetic base for my other K&F ND and CPL magnetic filters as well as the magnetic lens covers. All of the filters have threads, so they work either way. But when attaching a filter magnetically, the threads serve to keep the magnetically attached filters in place, which is great.

Stacking the magnetic filters works perfectly as well, as the magnets are strong enough to keep everything in place and stable.

All in all, these were far less expensive and yet more convenient than the other systems I looked at. I highly recommend them.

True story: I order a lot of lens caps because I lose them constantly. I've tried the little sticky straps and I lose them too. I have high hopes for this clever system. The UV filter, which seems like a solid filter, allows the magnetic lens cap to attach securely to the filter with a pleasing and reassuring SNAP. It isn't hard to remove the magnetic lens cap, but it does take some effort, which should keep the lens cap in place. I'm looking forward to taking this out on my next shoot.

K&F has been quietly making some great products these days. I already have their variable ND and CPL filter which are amazing in their own rights. However, this takes the filter to the next level. If you are like me, I am constantly loosing the cover as I remove it for photography and then I forget to put it on. However, with a magnetic cover, putting it on makes it so much easier. This in turn protect the lens against the elements.

The UV filter by itself fits perfectly and appears to be of good quality. I will be putting it up for a spin soon to test it compressively but from what I have seen, it's of high quality. I am quite happy with this package and highly recommend it.

I was amazed when I pulled the cap off because I honestly could not see the glass in the filter itself. No matter how I angled and turned the outer ring the glass reflected nothing. It wasn't until I put the cap back on preparatory to screwing the filter onto my lens that the inner surface of the cap reflected a light directly above and enabled me to see the inner glass.

I installed the filter onto a standard Nikon 50 mm lens and putting aside the question of whether to use this type of uv filter to protect your lens I have noticed no distortion or light cast in photos. Because the filter has matching 52 mm thread on the outside you can stack filters on top of it.

The only problem I experienced was with the magnetic lens cap which, actually, was the main reason I ordered the filter and which I imagine is their big selling point for this line of filters. The problem is taking the cap off the filter - because the grooves on the outside rim of the cap are horizontal to the plane of the lens there is no way to easily grip the cap and pull it off. K&F should have used raised horizontal striations which would allow easier gripping and removal of the cap. After a while shoving your fingernail into the very small groove between the lens and cap gets tiring and takes longer to use than the industry standard push in tabs. On the other hand the cap snaps onto the filter quickly and securely. I have tried to show these 2 factors in the short attached video.

Other than the aforementioned issue with the cap this line of K&F filters with magnetic caps are a really good fit for your photography and the K&F Concept line is frequently recognized as a high quality product. I give this K&F Concept filter with magnetic cap a solid 5 star rating.

I have put this on my 50mm lens which has filter thread of 67mm. The filter seamlessly gets attached to the lens. The filter is UV filter which is magnetic, which allows me to put on other compatible ND or other filters on the top of the UV filter.

It also comes with a magnetic lens cap, which is lightweight and great. The product quality is excellent and the filter doesn't change the photo quality. The filter also protects the lens from dirt and scratches.

This is a great little UV lens magnetic kit. I've been transitioning over my lenses to the magnetic filters, and my last purchase was this UV set. This set is different from the others because the UV filter is the magnetic adapter. That is to say, the magnetic ring that screws into the filter threads and the UV filter, are one piece. To add a ND or circular Polarizer, say, you just stack it onto the UV filter, and it stays very well. I'm quite happy with this filter because besides the strong magnetics , the glass is easy to clean, one of my main requirements. It also seems compatible with my Kase Wolverine filters and my ICE filters, always a good thing. Lastly, the lens cap sticks magnetically really well. I'm very happy with this set because it also seems tough. One of the main reasons I used a UV filter is for protection, and I think this will protect the front element very well. traditional screw-on type
