I am a huge fan of Black Mist Filters, and I was really interested in trying the K&F Concept Black Diffusion filter to see how it rated against some others that I have in my bag that on average cost twice as much as the K&F.

The K&F Black Mist is really well built and there are no flaws or flares that I can see anywhere on the lens and the mounting is rock solid and easy to spin on to my 67mm filter ring for my iPhone.

Performance-wise, K&F is top-notch. When I use a black mist filter it has to soften ever so subtly and for me, the best result is one that your see but don’t see. If you look at the video screen grab photos, you can see the difference although you may not see them instantly and that is the true mark of an exceptional mist filter.

The photo is a screen grab of a short video where I used the K&F in one shot only which is less than 2 seconds in duration. Simply adding the K&F resulted in a much more cinematic feel before changing to the next shot. I am thoroughly impressed with this Black Diffuser filter and wished I had considered this when buying another much higher price that offers me little to no added shot advantage.
