I loved the packaging, and the leather case it's perfect for storing. The filter itself seems sturdy and very high quality. However, for photography, you shouldn't use it to the extreme because the X appears around the 8th stop. But I'm very satisfied with the price-performance ratio.

I've been after this filter for a long time, and it only took one day to try it before I fell in love. It gives photos a beautiful cinematic look and adds more personality.

I was undecided between this one and another brand. But I don't regret anything else. The quality is very good, and the filter is solid air. So go for it!

It gives a brutal touch to the image and the construction is very good. 100% confidence

It's almost half the cost of a tiffen and works just as well. The build is really nice and I love the protective case. Took it to Vegas and took a bunch of shots of Freemont Street at night and they turned out perfect. Great buy

It is not a great value for money since filters from other more well-known brands cost the same (or a minimal difference), but you have a high quality filter in your hands. It does exactly what it was designed for without altering the colors in the slightest or creating chromatic aberrations. I use it in the video field where it helps a lot to diffuse the highlights giving the film the classic cinematic mood.

Very happy with this filter.

GENERAL IMPRESSION

This is a filter similar to the very well known "Black Pro Mist" filters used in movies. There's a number of reasons to use this type of filter like:
– smoothing up the whole image while still retaining important details
– making the transition from highlights and blown out areas to the surrounding areas smoother (it basically creates a "glow" around the brighter areas).
– when you have people on the screen, it helps masking out skin imperfections and giving that classic vintage Hollywood look.

At this 1/4 intensity it really brings in this smooth vintage look, but if one decides to go up to the full diffusion option it can add a very dreamy effect. That's a decision to take carefully as this type of effect cannot be undone on post, it's baked to the image. On the other hand, this type of effect cannot be done with the same quality on post. It's really a decision to be made at the film set (preferably discussed BEFORE the film set between Director and DP).

QUALITY

The built quality is very good. The filter itself is made of good quality glass and it is fixed to a metallic threaded frame. It comes also with a very sturdy metallic protective cap, also threaded. Bear in mind that because the cap is threaded, there's no "quick release", so it takes some time to attach it and detach it from the filter, which can be not very practical in some situations when work speed is a factor.
Filter and cap fit perfectly in a convenient protective hard case.

In term of optics, I took time to take some measurements with a light meter and a color meter and as a result I discovered that at this 1/4 intensity, this black diffusion filter eats up 1/3 of a stop (your image gets slightly darker). On the color side, it performs very well as a didn't notice any color shift caused by the filter.

CONCLUSION

This is a very good filter! The fact that it does not cause any changes in color and eats about 1/3 of a stop of light only, makes it consistent with another filter I have from other manufacturer, but different diameter. That means I can use both in the same job without worrying about overloading post production with avoidable corrections and adjustments from take to take when using different lenses.

My hairless Xolo dog is an extremely difficult color to capture, so I was excited to find a filter that might help with the harsh shadows. It works great!

I love the dreamlike quality it lends. It lets a bit of light leak into the shadows, which stops the hard black I kept getting when I take photos of Kai normally. I love the softness it lends. I took Kai out to a cornfield for some test photos and it did not disappoint. I also liked the effect on my kiddo playing around at Golden hour. I feel like this is a great tool to help me capture more spontaneous photos of my dog.

The effect is very subtle and I’m curious about what else it can do. The one thing I don't like is that the lens cap is metal. I have a mild tremor and my hands can be clumsy. I'm afraid of scratching the lens with it. I also have difficulty getting it off at first if I accidentally screw it too tight. I wish it was a plastic pinch cap like the others I own.

I received this item for free through Vine for an unbiased review.

I have quite a few K&F filters, they are my favorite and this one is high quality like all the rest. They just make them so incredibly well, with a fantastic fit and finish. Not to mention a study quality case and heavy duty well-crafted lens cap.

I picked this up for my GoPro 9 rig that has a 52mm threaded ring. Of course it screws on and fits perfectly. I use the rig on my electric scooter and this will be a nice diffusion filter that so far is giving me even better video output. Very happy with the results.

High quality, fair price, would gladly recommend.
