A good quality "square" filter system for photography. One thing to note if you are considering this system, the adapter ring kit does NOT come with a 55mm ring at this point. I raised the issue with K&F through their Facebook page and a response to that said the point would be shared with the appropriate people. Who knows, maybe it will come with a 55mm ring soon. If you need such an adapter for one of your lenses, you have to buy it separately. That means it's well made and sturdy enough to last for years I think and apart from 55mm there's a fair choice of adapter rings in the kit, eh

I own quite a few K&F Concept Products. They provide quality products without the hefty price tag we're used to see in the photography world.

Let's talk about the filters individually first. All 3 filters are of top quality, at least on this price point/tier, as we're used to get from K&F Concept products:

-The CPL Filter has no color shifting and performs as expected.
-Same with the ND1000, although i don't use 10-stop filters that often (my most used filter is a VND Nano from K&F Concept) during my test it worked well, no cross present, even while using step-up rings.
-The UV Filter has no color shifting and the main purpose these days of the UV filter is to protect the lens surface, BUT, It is where this VERY MINOR issue this kit has: The magnetic ring holder.

The magnetic ring holder works great with the ND and the CPL, just not as good with the UV Filter, but it is not by ANY MEANS bad or i'd call it unsecure, at least not on the 82mm filter size version, your mileage may vary depending on the kit size you got as the magnetic surface may be different for your version, just the grip doesn't feel as tight as it does with the other two filters and there is a TINY bit of play, but not enough to warrant losing a star over it, i mean if you shake the camera at full strength you may drop it, but on regular usage i do not see it just falling off the ring holder.

As the sum of all parts i'd say this was almost perfect. This kit complements my VND ND2-400 and includes everything i need to cover all my filters along my step-up rings. The UV filter thing doesn't make it lose a star, but maybe half, so i'd say 4.5 but since there's no option for that if i had to decided between 4 or 5 stars, i'll go with 5.

I've had these lens filter kit for a few months now. Unfortunately, the magnetic base ring got warped probably from pressure on my bag. They replaced it without any hassle. I would suggest keeping the base ring in a non-bendable case which is what I will be doing from now on. I would definitely buy from this seller again!

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.

This has been a good kit and is nicely made. Thumb screw to lock on to lens ring is a bit poor. Threads are not smooth, therefore difficult to tighten and undo. Although the filter box is extremely well made, it is very heavy and I am looking for an alternative.

This magnetic filter kit is just great!
It includes a neutral density filter, an MCUV filter, a CPL filter and the magnetic adapter ring.
Little extra, the presence of the storage pouch that allows you to carry everything well without damaging it and which is also waterproof and small enough to be attached to the belt!
Quality is at the rendezvous, with each piece packed one by one in moisture-proof packaging.
Once in place, it is possible to leave the adapter ring since it does not hinder the putting of the cover in any way.
Then simply place the magnetized filter of your choice and that's it.
The effects are great, beautiful and high quality.
The fact that everything is magnetic is a real time saver!

Bought in 2023, after a long time I feel like giving a review because it is the best lens of my kit. It has been used on Canon APS-C and now full frame Sony and has allowed me to take great shots home. Since it's wide-angle (so with a wide hyperfocal) you don't have to spend money to buy the autofocus version and the focus ring allows you to set focus very precisely and fluidly, but I'm sure that You will keep it in an infinite position 90% of the time. The other ring of the cone port is very useful and well made, with clicks that are easy to "hear". The sharpness is great, it loses slightly in the corners in full frame, but still remains excellent. Vignetting isn't a problem at all and closing the aperture at f/4 isn't as noticeable. I didn't notice any discrepancies in any of the many recordings. The aperture of f2.8 allows this lens to be used even in low light conditions or for those who want to take their first steps in the world of astrophotography. The downsides are minor and negligible: the outward weight distribution, the fixed lens hood, and the aperture ring partially covered by the built-in flash. I think this is the first lens to buy for those who want to "ditch" the kit. You will always carry it with you.

This tripod is great. It’s light, steady, tall and with the included shoe, the camera goes on and comes off easily. Best part is how easily it sets up. Love it.
