The K&F Concept Magnetic 62mm Lens ND Filters Kit (5 Pack) GND8+ND8+ND64+ND1000 + Magnetic Filter Adapter Ring Filters Set with 28 Multi-Coated for Camera Lens:

This is an outstanding ND filter kit. The filters themselves are very good ND filters with no color shift. I have been using several K&F Concept filters lately and I find them to be among some of the best I’ve ever used. Overall very well engineered and constructed. This kit comes with 3 levels of neutral density and 1 graduated ND. The filters attach magnetically to a screw in ring, making swapping them out quick and easy. The magnetic ring is pre attached to one of the filters when the kit arrives, and you will use that one ring for all 4 filters. I really love the addition of the gradient ND as landscapes are one of my passions and this filter is ideal for bringing drama out of the sky. The kit also comes in a very nice filter wallet with several ways to attach it to your bag, belt, tripod etc. This is such a nice touch, and it really is a nice wallet, not just a cheap holder. I highly recommend this kit if you are looking for high quality ND filters. If you love to shoot very shallow and wide open, these are a must have. Solid color rendition, well designed and well made, high end filters.

Many of us have caught filters solely to protect the lens, but not only do you achieve that with this kit, the UV filter is totally correct and the polarization took the hassle out of taking photos at the beach. Good value for money for me.

I'm a photographer and I like to add accessories to my kit. One part of the “kit” that was elusive for me is functional, easy-to-use lens filters. I have a great set of variable ND filters, but the only thing I keep struggling with is getting them lined up just right to screw into the lens. A surprising budget-friendly accessory maker, K&F Concept has a really cool set of magnetic lens filters. You don't waste time taking photos and trying to spit the filters properly. I think this is a great filter system. The filters are well made and of high quality.

I have a great set of variable ND filters, but the one thing I keep struggling with is getting them lined up exactly right in order to screw them into the lens. K&F Concept, a surprising, budget-friendly accessory manufacturer has a really cool set of magnetic lens filters. The set comes with a soft-sided, waterproof carrying case, adapter ring, MCUV filter, CPL filter, and ND1000 filter. The idea behind this set is that you screw on one adapter, leave it on the lens, and then pop the filters on and off as you need them. You don't waste any time while shooting trying to get the filters lined up just right. I think this is a great filter system. The filters are well-made and high-quality.

I mounted the kit on a lens with the 72 mm ring and it fits perfectly. It's easy to assemble and its operation is very simple, it doesn't require reading the instructions (I'd say it's better not to read them) just seeing the illustrations is enough. As for the quality of the product, it seems to be made with good materials and the finish is excellent; the polarizing filter holder is very effective, placing the filter well and with care and you don't touch it at all. There are two compartments for the square filters that I hope to get the most out of, I'm happy.
As for the optical quality of the filters, I can't comment because I haven't used them yet.

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.
