Until now, I really haven't tinkered much with diffusion filters as I mainly get the desired results with Photoshop and a brush. Keen to try these, I must say that I did like the results.

Caveat - I did most of my shooting with these filters using studio off-camera lighting and a range of modifiers.

The effect can be subtle or more dramatic depending largely on your subject and their skin/texture/features couples with how you like to light your scene/subject. A softer light on a subject with mostly clean/flat skin yields a nice dreamy effect that doesn't look too manufactured or plastic. With more harsh lighting even with the same subject, there is a softening effect yet is reduced due to lighting. I did stack the filters and was significantly softer under hard light but not as soft as the previous setting.

I did use these diffusion filters on a model I shoot very frequently and asked her to not do much to smooth out her face (she has little acne scars). I used both soft and hard lighting with the filter attached (went back to single filter) and the results were much more noticeable. I was happy to see that, again, didn't look too manufactured or over the top. I did double-up the filter and again the results were as expected with the amount of softening.

As far as highlights are concerned - this did aid in highlight control without squashing them out. Specular highlights were still visible yet muted down (based on a control image). It's not negligible but if you're not comparing to a control image, you probably won't see too much difference.

NOTE: To better enhance your effect make sure you have any in-camera sharpening turned off (which you should do anyway..LOL) and if you're tethering (Lightroom or Capture One) also make sure you're not sharpening! I am a big Capture One tether shooter and have found that CO does tend to add-in some sharpening on its own (compared RAW shot to card and same file saved to my computer in the CO file).

Other items - these filters did not cause any significant color shift (I meant to use my DataColor cards and.. well, didn't.. sorry..) or stop-down any light. The filters are very well made, the threads are nicely machined and finished, and come in a nice filter holder pouch.

While I may not use them for all shoots, I can (and have) used them for clients needing that little extra 'something'..

These days lenses are super sharp. So now we want to mimic some of those all vintage lenses from the past, which were a little softer, etc.

This diffusion filter won't come off from my 50 mm ever. The haziness that offers around highlights, is lovely, giving a ver nice look to photos.

When filming is fantastic as well!

For starters, the filter came packaged better than I expected. It arrived in a nice faux leather case for safe keeping or traveling when not in use. It is also very well made and dare I say rivals some of the more expensive ones that I have in terms of quality and performance. It was a bit difficult to get onto my lens, I had to carefully line up the thread but once it was on my Fujinon lens, it did not budge. It was easy to adjust while shooting and wasn’t too loose that it moved on its own.

I’ve never used a diffusion filter before so I wanted to try something new when it came to my images and I’m kind of sold with this one. It added this softening effect to my images, smoothed out some of the edges but still kept the details.

So.. I'm going to be up front.. I'm NOT A huge fan of diffusion filters. People already tend to over-soften their images they post online, so I'm not a giant fan of a 'dirty lens' look.

However, for some of our sessions we've done, soft images are more desireable than hard/crisp images. (An example, is if you're producing an image that appears to be in a fog or smoke) In the past, I would have simply used an oiled UV Filter (that's literally what it sounds like... put a light layer of oil or grease on the filter, and then attach it). As you can imagine, while those images turn out ok, introducing oil/grease/vaseline into gear, is always a nightmare. So, diffusion filters are a go to, for many photographers.. now myself included.

Black diffusion filters by and large, are used for 2 purposes.. 1.) Soften images, and 2.) reduce highlights/glare.. To that end, these 2 filters serve their purpose well.

However, I will point out, for MOST use cases, while the 1/8 can be used as an all around every day use filter (if you so desire), I would strongly recommend taking the time to find your use case for the 1/4, as it can drastically change your image.

As for these particular filters, they do their jobs, as expected.. EXCEPT, there is one thing I REALLY want to point out: These are double threaded filters, in that you obviously thread them onto your lens, BUT, these is a thread on the external side of the element too, so you can couple this up with other filters, as well.

THAT is a major design decision, that I honestly wish more manufacturers would take the time to implement. It's often frustrating, when you're trying to couple up multiple filters, and yet, you can't.

As with all K&F filters, the easy twist to open case for the filters are amazing, and the fact they have multiple rings, so you can store a different filter in their case, is a bonus.

However, while the fact that you can store other filters in the case is a plus.. it can also be a minus. If/when you have multiple filters of the same manufacturer (in this case, K&F), keeping track of what each filter is, in each case, especially while in studio, can be a challenge. So, it'd be nice to see a label on the case, indicating what is inside. Still, that's something that a simple label maker could do, too, so it's not a big deal... just one thing I've always noticed with multiple manufactures, and is NOT limited to K&F.

K&F claims there's an anti-scratch coating on their lenses, but short of taking sandpaper to the filter, I cannot attest to that claim, until I've used these longer than a few weeks. That said, I have no reason to doubt this claim, as the other couple of K&F filters I've used, seem to have held up well.

So far, I'm quite happy with these 2 filters. They soften the images, without adding any real color shift. They are comparable to a significantly more expensive set of filters that I've been using for years... so much so, in fact, that I'm thinking about giving more of the K&F brand filters a go.

These are an amazing set of filters, and I'm quite happy to have them in my studio gear collection.

I bought this filter to remove the sharpness and the too digital look that today's cameras have. The quality of this Black Pro Mist from KeF is excellent, the result is identical to the more expensive filters from Nisi.

The effect it gives is mainly marked when we frame light sources, creates the halo of light around the main source, whether it is the sun or an artificial light.

Great for giving a vintage and particular touch to your photos / videos

When I first found out about this lens filter, I knew I needed it. I've spent so long in editing programs just to get a subpar hazy/soft affect on my photos, but this filter is what I've needed this whole time to streamline my photography workflow. It's the perfect filter for that dreamy film affect!
The top photo is without the filter, the bottom photo was taken just a second later with the filter. It ads a beautiful softness and warmth to the photos!

Well made and adds a very subtle change to your photos and video that make them feel more real. Adds a light smoothness and maintains sharpness well.
Great product sold in with a solid protective hard case.

Nunca quiero quitarlo de mi cámara.
Da un brillo suave realmente hermoso y me encanta esta adición a mi kit.

"K&F concept 62mm black diffuser filter 1/1 black fog softlight diffuser lens filter" is very good, h is very suitable for my Nikon camera lens. This filter can have a good effect on portraits.

Very happy with this filter, the diffusion is great.

The price is also great, I had one that cost me 3 times more but the quality is the same.

I recommend.
