This K&F Concept Magnetic 58mm Lens ND Filters Kit is surprising good quality, everything from the packaging, to the storage carry case, to of course the filters! They fit my fuji xt2 stock lens perfectly. I do wish there is another GND filter in the kit. The magnetic filter snap on and off easily (but carefully!). I am not a photography expert but these seems great quality! I am very pleased with this K&F kit.

I now have this amazing filter attached to my Olympus 60mm macro lens. The lens has no lens hood, a bad front cap and obviously no filter. This is now on board, along with a tidy front cap and third-party lens hood. 46mm is a little small and fiddly, but this one has a really good knurled ring that feels good in the hand. The thread is also very smooth and positive. The color balance is imperceptibly different, so it doesn't bother when shooting in well-lit close-ups. I love the improvement on this brilliant lens. ricky

I bought a Helios lens 58mm f/2 M42 for use on the NikonD5600. I use it with no problems. Thank you very much.

Fits perfectly on a 58mm lens. No impairment of the picture. Good lens protection.

I got the filter for my EOS 750D with 18-55mm lens. The 58mm variant easily fits on top of the lens. In a direct comparison with 2 pictures of the same motif you can definitely see a difference. The dark areas are more diffuse, only slightly, but the difference is visible. Beautiful effects can be conjured up with the filter lens.

Great for the price, does what I'm supposed to do.
Haven't tried this new one yet but I'm assuming it's the same as my 58mm I bought a few years ago. Great quality and I really like the packaging with the little tin to protect it when not in use. Also included is a handy little lens cloth. I only ever carry a 6-stop nd as I think it's a great middle ground for long exposures. By matching this to your lens and stopping down the aperture, you can always get the exposure you want, especially at sunrise or sunset. If you are shooting at noon, 10 stops may be preferable. Image quality is great and less color cast than many other so-called professional options on the market.

You can get an adapter ring for just under €5, in my case from 58mm to 77mm. This is made of metal, can be easily screwed onto the lens and the larger filters can also be easily attached. So I give it full marks here.

love it works great. However! If you have a 58mm thread, you need to buy a 62mm lens cover because the front thread is larger than the rear thread and the 58mm thread will not fit. Just a helpful tip when purchasing this product.
