I haven't used any magnetic mount filters before. It's really nice to have that. I didn't realize how convenient it would be not to have to screw and unscrew filters every time I want to make a change.

The diffusion effect of this lens is easy to notice if you're looking for it, but subtle enough that it doesn't call attention to itself. I was concerned that it might be too much at first, but I like the results. I didn't notice any color cast either. Very nice filter. Does the job well.

I took some fantastic pictures of my grandkids with this K+F 1/4 (67mm) Diffusion filter. Ok, they are my grandkids and incredibly beautiful and photogenic, but this filter really made the pictures pop. It softened their skin and actually revealed more detail. I use a Nikon 750 with a Nikon 85mm 1.8 lens. Normally, I use a B+W F-Pro filter, which is really bright. Most of the pictures I shot with the K+F diffusion filter on top of the B+W filter. It is incredibly to attach the K+F filter. You just screw in the ring and pop in the filter. The latter attaches magnetically, but it's a pretty firm attachment. The filter comes with a lens cover that is also magnetically attached, but not so firmly. I noticed it tends to detach when the camera is jostled a bit in my camera bag. That's my only reservation about this filter. I also took off the B+W filter and used the K+F as the only filter on the camera. It works fine, but I prefer using both: I like the effect and I am also incredibly lazy. The good news is that even with two filters there was no vignetting.

I have only started buying K&F filters in the last 3 years, but there is absolutely nothing negative to say about them. I love the filters from K&F.

This type of specialty filter is a bit pricey so I usually buy the size that fits my largest lens. That jacks the price up even more, but I use adapters to enable using them on smaller lenses.

I don't mind paying for quality, but I am frugal none the less!

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 use a Fujifilm X-T3 camera and got this to go with my 55 - 200mm zoom lens. The mounting ring attaches to the lens without issue and I am a big fan of the magnetic attachment for this filter. There are many different brands of diffusion filters out there. I have used Tiffen brand filters in the past and always been happy with them but when I came across the K&F filters I definitely wanted to give them a try.

I have used K&F products in the past and have been particularly happy with their lens adapter system (I used to shoot with Pentax cameras and lenses and their superb lens adapter has allowed me to use my old Pentax lenses with my Fujifilm camera.

This magnetic system does not disappoint. Swapping filters is super easy with the magnetic attachment system. The lens cap for the filter system has been criticized by some but I find it to work very well. It actually reminds me of some of the lens caps from my Pentax system so I felt very comfortable with it.

As for the quality of the diffusion - excellent! I really enjoy the softer look that this diffusion supplies without it bein too heavy-handed.

I was a bit surprised by one thing however. I expected to be able to install this filter system and then still utilize my tulip-shaped lens hood but I cannot do that when this K&F is attached to my lens. To be honest, I wouldn't be surprised if this is really the fault of the Fujifilm system as I have found their lens hoods difficult to attach compared to other camera systems I have used in the past. That said, I intend to get some more K&F brand ND filters to take full advantage of this magnetic attachment system. It's a winner in my book.

The “mist” diffusion filter does what it advertises. It’s a softer image with “blooming” highlights especially if backlit.
I double stack my filter with a prime lens effect dream filter for an extra dreamy look.
I totally recommend this.

I've always been of the opinion that photo filters and lenses are expensive, though I recognize that good glass and coatings aren't cheap. This filter, though...the results are magical. Golden and blue hour photos take on soft mystical qualities, fairy lights turn into will-o-wisps rather than bokeh, skin imperfections are evened out somewhat, and it does a better job than my old soft-focus filter which tended to lighten shadows too much. It's THE filter I reach for if I'm trying to create a fantasy atmosphere, and can make even a photo of a garden gnome look plausible.

I love the way this has the magnetic ring mount, though I'm sad that most of my other filters are screw-in and therefore can't swap easily with this. Perhaps someday I'll be able to get more; my filter stack was mostly built in the early 2000s and could use a few upgrades. This one's worth every penny of its list price for the results.

I have the K&F magnetic system on all of my lenses, and got several of the matching ND and CPL filters in addition to the black mist one here. They're so convenient, easily stackable and the connection is strong enough that I don't have to fear that one of them could fall off. The black mist effect here is very minor, and only really noticeable with plenty of backlighting. Many cheaper filters often have a color cast, but I haven't noticed that with the K&F ones at all.

The only downside is that on my Sony lenses at least the magnetic caps that are included are really hard to pull off when you have the lens hood on the lens (either forwards or backwards). Some grippy element at the front of the cap would've helped with that. I might 3d print some holder and glue that on there to fix it. Since the caps aren't really the main reason to use a magnetic filter system though I'm still giving 5 stars, they would've been a nice bonus if they worked well but they're not really critical to the product.

I bought this filter to test it out vs the Tiffen brand pro mist and it did not disappoint. Theres a video on YouTube that compares these two filters side by side and the K&F is definitely a competitor. Price is fair which I liked, it came in a nice container as well. In my opinion dont overpay for the Tiffen.

High quality materials
