A good filter that keeps what it promises. Unfortunately, I bought it too late, on the manufacturer's website it cost around € 50 for a long time, now all of a sudden it doesn't anymore. I find the effect too extreme for outdoor shots, although of course it always depends on the scene and the desired result. But you can certainly recommend him.

Very good construction and definition.

Nice filter. Definitely comes in handy in certain situations. Great for sharp lenses, especially those with no character. That brings some mood. It's nice to have, looks good, and I love that I can apply it to a lens and still use the lens cover over the filter when it's not in use.

The lens is extremely well made and the effects this filter can provide are superb. Excellent construction with precision threads as well as magnetic instant on/off capability. The NANO multi-coating is superb and does NOT produce any artefacts, focus issues or any other issues.

Black Pro-Mist 1/4 filters are used for a number of purposes, not the least of which is to soften skin contrast and create a "dreamy" effect for portraits and general subjects where softened contrast is desired.

This 67mm set is a widely used size of many lenses. For me it's the right size for most of my Tamron lenses as well as the Sony 85mm f/1.8, Sigma 16mm f/1.4 APS-C and my Canon 100mm f/2.8L macro lens. That makes this single filter set an excellent value for the already low price on Amazon.

This particular filter model offers 1/4 diffusion that creates a softer, cinematic effect and is great for both stills and video. This K&F version uses a unique magnetic adapter that screws into the front of the lens and allows 1-second attachment of the Black Pro-Mist 1/4 filter for easy use and removal. Turn on/off immediately.
This makes it incredibly easy to use a camera with or without a filter and not have to screw it in and out repeatedly. Great innovation!

As a YouTube video producer, influencer and vlogger, this filter has been fantastic for spontaneous shots and videos when I see a scene or shot that would benefit greatly from some softening... especially of people for live action or portraits when outdoors record in bright light or sunshine. Shadows are not affected and reflections are softened somewhat. Perfect!

I own a number of K&F filters of various types including UV, ND, polarizers and diffusers. I have placed great trust in the company's products without hesitation. This particular filter set offers excellent value for money when compared to much more expensive similar filters such as those from B+W and Hoya whilst offering virtually equivalent performance. Fantastic!

For me, this filter is clearly a Strong FIVE STAR winner and gets my honest and VERY warm recommendation! Simply excellent!

Overall very satisfied with the filter, great quality, I bought the 52mm version, used 2 of my kit lenses and no problems. Very easy to install and remove from the lens. Easy to clean. Should last a long time.

Magnets are magic. Don't get me wrong, these magnets just aren't quite as strong as I would prefer for something covering my expensive glass. The Black Soft Diffusion Filter is interesting. Wouldn't be my first choice next time, but it provides an interesting softening of light sources like campfires, night lights, etc. A bit spooky, but subtle.

Perfect for portraits. Try it.

This filter made a deep impression on me, I really didn't expect it to be so useful for video production. I think it's enough for me to shoot a video on a sunny day.

The Diffusion Filter "Mist" does what it advertises. It's a softer image with "blooming" lights, especially when backlit.
I double stack my filter with a Prime Lens Effect Dream Filter for an extra dreamy look.
I can only recommend it.

Ideal for outdoor shootings in the morning or evening in deep sun
