I had used a popular UV filter before. It's not bad. Only under certain conditions would there be glare or aberration. For the most part it worked fine. But it still bugged me. So I ordered this K&F UV filter. WOW! What a difference! The glass is SO clear you can't tell it's in the housing! And that is how clear my photos became with it on! Definitely worth the price difference! All my filters are now K&F brand. The quality is outstanding!

As most K&F products, the build quality of this filter is quite nice. The threads are smooth, filter ring is powder coated and then optics... well, hard to say they're clear or anything since they're a diffusion/soft filter, but the picture quality is still quite good. More on that later.

The filter comes in a circular filter case that is one of the neatest filter cases I've seen! If they don't sell those as products yet, they honestly could! There are raised partial circles that allow you to place all sized filters in the case, unlike most with a foam cutout (which, admittedly offers more padding). It would be nice for the filter case to have a small sticker on it to indicate what is basically on the box--"NANO series 52mm MRC Black Diffusion 1/4" in my case.

The optics look like a clear glass with a bunch of small grey dirt specks. That is the intended design. The effect it creates is a soft diffuse glow; a bloom effect. The contrast is lowered when using this black diffusion filter and overall it looks like a similar effect to a soft filter. The sharpness at the point of focus isn't too affected though, so it can still be used in portraiture as well as in other creative photography. Light sources will bloom when looking through this filter. I find the 1/4 strength to still be quite useful while the 1/2 an 1 may be more niche.

Best black mist filter I’ve ever used. Sharp image with a subtle soft glow.

Conforms to the description and exceeds expectations

The product came in beautiful packaging and with a handy case that can be used to keep several filter sizes. The filter looks nice and without any glare. I took several photos, which look wonderful. I haven’t explored many lighting situations yet, but since my main reason for the filter is to protect the lens, I am satisfied.

Perfect to create beautiful pictures with a vintage look. Delivered in a round box. The material is also handy and handy, very high-quality workmanship.

Order received on time.
Packaging more than adequate.
As for the equipment more particularly well… it does the job very well. It's really essential gear for those who want to soften their digital photo rendering. Can't wait to test it in portrait photography

I really like the soft light that it produce in videos. It's especially noticeable in "color lights". Made everything more dreamy and cinematic, especially at night.

Really nice quality filter, comparable to more expensive brands. Has that black pro mist look. Softens things and gives lights a bit of glow. The he 1/4 does enough but id be curious to play with the stronger versions too.

Great price.
