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 like my K&F Concept 58mm Magnetic Circular Polarizer Lens Filter. It fits well magnetically or screwed on. The quality of the filter is very good. It also comes with a lens cap safely stored to protect it when not in use.

I recently purchased a lens with a 58mm thread size, so I was out looking for a UV filter to protect my investment. One of the first things I learned about photography is that it is always cheaper to replace a filter than a lens due to an accidental scratch or abrasion. When you are out and about, you also don’t have to be paranoid about wiping off the surface of a filter, which often happens when you do not have the time to do it properly with a blower or a cleaning cloth.
I have K&F filters on almost all of my lenses and have not seen any noticeable issues in using them. This package included a cleaning cloth, lens cap and a cap lanyard. Personally, I like to keep my OEM lens caps safe at home. If you sell a lens, it will always look a bit more attractive to most buyers with the original cap be it Canon, Nikon, Sony, etc.
The lanyard is orange colored and very well made compared to others I have. Regarding the cleaning cloth, you can never have too many of these on hand. All of this was packaged in a clear hard plastic case which could be used for other items.
For the price, I consider this to be a very good package to buy.

I tried the ND1000 58mm on my Nikkor 50mm 1: 1.8G. It was really very bright and you can see what came out of nd filter in the photos. :) I can only recommend.

This is a diffusion filter for cameras. I have the variant for 58mm filter threads. The Black Mist 1/4 filter creates a more softening effect. It looks nice, but you really have to look closely to see anything. However, you can see it in a direct comparison. In any case, it's not "too much". The filter is well made and fits every lens and camera with the appropriate filter diameter. (I tested it on 3 different cameras)

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.

The filter comes safely and neatly packed and with the 58mm thread it fits perfectly on the Canon lens of my SLR camera.
The photos get a slight blur from the filter, which usually makes them look a bit warmer. If you only need part of a photo or want to enlarge a section, you will have to unscrew the filter beforehand.
All in all, and especially when there is backlight, the 1/4 filter is a small addition that also reliably protects the lens of the lens. I wouldn't consider it a must-have, but for those special moments the filter is definitely worth the money.

Everything perfect
