K&F is really making some fantastic filters as of late. The build quality on these are excellent. Precision machined brass rings that are thin enough not to interfere with the image but strong enough to protect your glass. They screw on very smoothly and the brass will prevent stripping and cross threading.

The optical quality of the glass is excellent. There is no distortion whatsoever and the mist filter gives your images a very subtle dreamy quality. Something really impossible to do in Photoshop or with digital editing in my opinion. You get the realism and quality of an actual optical effect, and these look absolutely beautiful. Some people may disagree but I always prefer doing as much as you can in camera to eliminate the need for post processing. And of course for video it’s definitely a timesaver. Applying this subtle mist effect digitally in video is very processor intensive.

This is a nice little way to soften the features for portraits and I decided to take a portrait of this little fellow. You can really see the difference around the eyes that the filter makes in addition to the fact that it was really bright and this filter helped soften the shadows.

This is a 1/4 Mist so the effect is very subtle. Don’t be confused by the name black diffusion. This filter will lighten your images by reducing contrast and softening highlights. It actually lightens up the image a bit but in a way that doesn’t create blurriness. That’s the beauty of genuine optical filters rather than digital post processing effects.

This is comparable to my German filters that I paid a lot more money for in the past.
