Let's start at the beginning. What does a "crap filter" do? It ensures that lights get a "blurr effect". In German the lights look a bit hazy. This can create a really cool look in film productions, but is also really useful for photos for portraits etc. For example, a chain of lights in the background of the model or similar

Autofocus works perfectly with the Sony A7 Mark 2 and the Kito lens.

What I find absolutely awesome is the "packaging" or where the filter is stored. Nothing wobbles here! This is rock solid and can even be used for other filter sizes.

Oh: Despite the filter, the lens hood and the protective cap for the lens fit without any problems.

Processing as always top! no plastic ;-)

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!

I've used this filter a couple of times for my creative photography and videography in a couple of instances and i can tell you K&F Concept nailed it again.

I can't post images of content i was paid for due to contractual reasons, but this is definitely a professional grade filter.

I noticed no image resolution degradation, no white balance issues, no vignetting or distortion when the filter was on.

It arrived on a rather large protecting case that i discarded right away and it was unwieldy, hard and larger than it needed to be, but i own a K&F filter pouch (shown on pictures, not included with the filter) that i use.

Despite not liking the carrying case, this is a GREAT Black Mist filter, it feels premium on your hands, mounting was smooth, it feels sturdy and while i did NOT test scratch resistance i trust K&F Concept products.

Great value for a premium filter, i would recommend it to anyone who is in the market for one.

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’ll be honest up front, I ordered this mistaking it for an ND filter, I’ve decided to keep this though as I really like the effect it produces.

I’ve been getting into landscape photography and wanted an Nd filter but ordered this by mistake, after having a play and wanting to eventually push into portrait I decided to give it a try.

The results are surprising good, it adds a nice glow to bright light sources that give the images some warmth.

The filter is presented in a lovely case with rubber wedges inside that hold the filter in place so it doesn’t slip around.

I can see me using this for product photography and portraits and so far have really enjoyed it

Pros
- nice glow
- gives images a warmer feel
- excellent storage case

Cons
- none ( although keep in mind you may need to adjust exposure times slightly due to very minimal tint )

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.

Works as advertised. Portraits have a dreamy look to it but it’s subtle compared to the moment cinebloom filter. Construction isn’t as nice as the moment but images still look good.

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
