Nice filter, I use it slightly overexposed to give that cinematic look

I really like the magnetic features of this set of black diffusion filter and lens cap because it makes it so easy to apply to your lens! It was my first time using a black diffusion filter and I have to say it creates such an interesting effect by diffusing the light and increasing the contrast, it really gives it a dreamlike appearance that I did not think would be possible.

As I said earlier as well, I really like the quality of the lens cap; it is made from a nice high quality durable metal and has a strong magnet which makes for easy application and removal.

I tried on landscape and never noticed a difference, with portraits, needs to be figured out and is one more variable to the picture. I think the main use is for artistic stuff. The magnet cover is excellent innovation.

I have the threaded version of this filter from K&F Concept and I have been very happy with the quality of it. I use it regularly to give a subtle softening effect to my images. This new magnetic version is awesome! The magnetic attachment is very strong and it makes it so quick and easy to install or remove the filter and lens cap. Construction quality is excellent; K&F filters are very much in the same league as Tiffen filters. Highly recommended!

I see that K&F has started to produce a range of different filters (ND, polarizers, and diffusion) using this magnetic system and I would definitely be interested in adding more to my collection because it's a terrific system. It would work especially well for the 10-stop ND filter because that's the kind of filter you have to keep screwing on and off (because you can't see through it to focus), so being able to snap it on and off would make it SO much easier to use.

The quality at the rendezvous, the light and the faces are diffused as desired. Change and give a soft cinema look to all your shots! I have already tried cheaper filters but here I must admit that the filter does the job really well. Night shoots look better with it! At the top I recommend!

Decent filter!

Great filter and cheaper than competitors.

This filter is not the one I used to carry around in my bag on a regular basis, as I assumed it mostly worked as a mix between an ND filter and a soft filter. But, seeing the possibility of using it for a few days, I realized that I was wrong! The 1/4 black diffusion filter (there is also a stronger 1/2 filter) is primarily used for its softening effect on faces, where it can reduce the appearance of wrinkles and blemishes. In this role it works, but maybe a little too much for some shots. I shoot outdoor landscapes and architectural photos more than portraits, where the filter reduces glare and reflections. It is also useful for defocusing backgrounds more than the camera itself handles. The effects, at first glance, are subtle, but they are visible in a side-by-side comparison. Most of the time, there is a “glow” effect on the snaps which is very appealing. The quality of the filter is high, and I now use it almost by default on my primary 85mm and 105mm lenses. Nice filter.

The lens is extremely well-made and the effects that this filter is capable of providing are superb. Excellent construction with precision threads, as well as magnetic instant on/off capability. The NANO multicoating is superb and produces NO artifacts, focus issues, or other issues.

Diffusion filters are used for a number of purposes, not the least of which is for softening skin contrast and creating a "dreamy" effect for portraits and general subjects where a softened contrast is desired.

This 67mm set is a widely used size by many lenses. For me, it is the right size for the majority 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 a superb value at the already great price on Amazon.

This particular filter model provides 1/4 diffusion that creates a softer, cinematic effect and is outstanding for use in both still photography and video as well. This K&F version uses a unique magnetic adapter that is screwed into the front of the lens and allows for a 1-second attachment of the Diffusion filter for easy use and removal. On/Off instantly.
That makes it incredibly easy to use a camera with or without filters and not have to screw them in or out repeatedly. Awesome innovation!

As a YouTube video-producing influencer and Vlogger, this filter has been fantastic for spur-of-the-moment shots and videos when I see a scene or shot that would greatly benefit from some softening...especially of people for live action or portraits when shooting outdoors in bright light or sun. Shadows are not affected and reflections are somewhat softened. Perfect!

I own a number of K&F filters of different types including UV, ND, Polarizers, and Diffusers. I have come to strongly trust the company's products without hesitation. This particular filter set is a superb value at the price as compared to much more expensive similar filters like those from B+W and Hoya, while providing virtually equivalent performance. Awesome!

For me, this filter is unequivocally a Strong FIVE STAR winner, and gets my honest and VERY hearty recommendation! SImply superb!

Very suitable for taking pictures of silky water. Good quality glass and threads are essential for any serious photograph
