My circular filter kit for each lens size includes a protective UV, a CPL and ND 10 and 6 stop. The K&F kits contain all but the 6 stop. The 6 stop can be ordered separately, though at this time only from the manufacturer's website.

For any given size kit, the K&F Concept magnetic kit costs far far less than would top line individual threaded filters from other manufacturers (Breakthrough Photography, B+W, Hoya HD3, etc.). Yet the optical qualities of these K&F have been tested and are equal to the best. My own experience is that the K&F coatings are also just as effective at repelling water droplets as are my most expensive filters.

Having used K&F Concept magnetic filters in two sizes for a few months I am loving the speed of filter changes and the absence of thread jamming when I stack an ND on a CPL.

My only criticism is the lack of knurling on the front edge of the CPL frame. Magnetic CPL filters do not need or have a two piece construction. The entire filter is rotated in its magnetic attachment, which is fine but remains a two-finger grasping maneuver. To rotate the CPL you'll need to temporarily remove the lens hood. Maybe had K&F added knurling to the from edge a fingertip would suffice, but there is more friction opposing rotation than in a well made two piece threaded CPL. Off course you could attached your old threaded CPL to the lens, screw the open ring magnetic adapter onto the CPL, then add your NDs magnetically. You'd risk jamming the adapter ring to the front threads of your old CPL. I'm not going to do this.

The protective UV is only meant to be attached directly to the lens threads. It is a lens protector. It does not magnetically attach atop the other filters or the open adapter ring. You are give two threaded adapters, one is just an open magnetized frame. The other has the protective glass. The CPL or ND can be clicked onto this protective filter, but not the other way around. My advice is to use the protective UV when facing blowing sand or salt laden ocean mist (and when shooting from a Russian reindeer sleigh where showered by flying feces).

The included pouch is well made and easy to use. If you buy kits in multiple sizes you can even combine them into one pouch by storing the filters magnetically stacked and assigning each compartment of one pouch to a different diameter.

This ND filter left a deep impression on me, I really didn't expect it to be so useful for video production. I think it is enough for me to shoot video on a sunny day.

It’s a great set of mag filters, and they are relatively budget friendly too comparing to most competitors like Kase, Haida or manfrotto. The magnets are pretty strong and the stacking mechanism is a joy to use. Keeps the package slim and works way better than magnetic filter rings from competitors.

One big complaint, is that the filter kit doesn’t come with a magnetic lens cap. The filters themselves are really shallow and won’t hold a clip-style standard lens cap. So without a magnetic cap I won’t be able to cover my lens. Had to purchase a separate magnetic cap from Haida to use with this set of filters……

I purchased this K&F Concept 67mm Magnetic Lens Filter Kit
for my Tamron 28-75 f2.8. These filters work great and fit on my new camera.quality looks good.
It was a great choice!.... It allows me to capture long exposure water shots on bright, sunny days. It's not a variable and it's too dark for those dark dreary, overcast days. You'll want a different filter for that. The filter is well made and easy to thread onto my lenses. It also comes with a nice case to store and carry. The images come out clear and sharp with no vignetting, like you might get with some filters. Great value, definitely worth the money. I am happy with this purchase.

More magnetic filters please

Works great.

Mine just arrived. I’m impressed with the quality. Can’t wait to try them.

I like how they are easy to use and saves me time and frustration from having to switch lenses.
I do wish that I could use my K&F 150x100 square filter holder with this kit.
It’s unfortunate that K&F did not create this kit with the thought of using it with the square filter kit though.
I do use a UV and CPL circular filter with my square filter system at times and not to be able to connect my K&F 82mm filter holder ring with this is a bummer.
I’m surprised it doesn’t work with it or that it’s not able to screw onto the magnet filters in this kit.
K&F please fix that in the future.

Typical of my experience with K&F products, these are excellent filters. They are every bit as good as a couple of other, higher priced, popular and similar products. No color casts, well manufactured, and simply work as described. Save your money and buy these over the more hyped brand names.

I bought these filters for my Nikon 49mm, and the result is really excellent. First of all, I found the packaging really well done, quality product. As for the filters, the system that holds them together is very reliable, protects the glass well and allows good portability in our photo travels. Personally, I found the lens really excellent as the quality and the final result. I recommend it to everyone from beginners to professionals because the performance is really great.
