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'..

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.

happy with these! Great quality

I have been using these filters recently for portraits and the 1/4 specifically has made a big difference in some of them. The effects from this filter have made the editing much easier and takes a fraction of the time that it used to. I highly recommend these filters.

these filters are more prominent with the bloom than the tiffen BPM i use however they have a more pleasing highlight rolloff and subtle contrast reduction. they flare a tiny bit if having a light source hitting the filter directly but overall they are very good filters and give a cinematic touch to overly sharp images

I have a Black Mist Pro 1/8 filter that I use quite a bit, and based on my recent positive experiences with K&F filters, I decided to give this set of 1/4 and 1/8 filters a try. Because the K&F filters cost about 30% less than the Black Mist Pro equivalent, they are perceived by some "pros" as lower-quality filters. I'm happy to say that these K&F 1/4 and 1/8 black diffuser is every bit as good as the Black Mist Pro equivalent, achieving exactly the effect I was after with no distortion or color cast. I also own the K&F 1/4 diffusion filter with the magnetic mounting system, which costs the same as the this two-filter package. While the filters are idenitical in terms of effect and optical qaulity, I really love the magnetic mounting feature, so you might want to consider that before purchasing these conventional mount filters (but if your budget is tight, you can't beat the price for two quality filters). The price to value ratio for theser filters is excellent.

I like diffusion with a light touch (any type). Mist diffusion filters in particular tend to become increasingly problematic looking as they get stronger. The K&F filters work well and are value-priced. Keep the effect targeted with a light touch and you'll be quite happy with them.

This set of camera lens filters are of excellent quality. I am very much an amateur and have only limited experience using filters and that was years ago when I was taking a couple of B&W photography courses with a 35 mm film camera. I do have two DSLR camera & lens kits which I have been experimenting with and when I saw these lenses I wanted to try them out. I am not as familiar with the Japanese-made glass used in these filters as I am with the German-made glass in the lenses and filters I used to have, but the optical quality of this AGC glass and the coatings seems to be top-notch. The filters are thin, light and strong, + they are also very clear with no imperfections noticeable to the naked eye. The light transmittance is very good, so even though I am diffusing the light, there is still enough. I really appreciate that this set includes both the 1/8 and 1/4 lens filters. I ordered the 58 mm version for my Nikkor zoom lens and both filters fit perfectly. i like that both of the filters have the external threads so I can also attach another filter over or under the one I am using. I haven't done that yet as I am still exploring what type of images I can get just using one or the other of the filters in this kit. The cases are very nice, as well -- they feel strong & sturdy. The current price of $69.99 for two lens filters seems very reasonable, and I will definitely look for this brand when I'm ready to try other types of filters.

I'm really loving the K&F concept diffusion set, it gives the wonderful haze like effect with halides on the lights and bloom to really give you that dreamy film like aesthetic. The great thing about it is that it also doesn't lower the quality too much of your images. It get's rid of that "clinical" sharp digital look and adds life to your photos. The packaging is great albeit a bit large for the filter itself but it's a nice little carrying case to put into your bag.
I love using the 1/8th strength for everyday shots and the 1/4th when you really want to amp up the dreamy look.
