Soften ups the image without altering the color too much, which makes things easier in editing if you're working from a LUT

Admittedly, I have never used a Black Diffusion filter before so this was a bit of a learning experience. The filters themselves come well packaged in a nice plastic case to protect them. They simply screw onto the end of your lens. The filters have nice grips to help enable you to put them on and take them off. There are also a few lens cleaning cloths included.

These filters fit easily screwed onto my Canon EF lenses. I initially tried a simple portrait shot before and after. The after image was slightly softened and some minor reflective glare was reduced to nearly nothing. I liked my After shot better than my Before shot in this case. However, it is important to note that the results you get will vary depending on your lighting.

Next, I set up a shot with a light source in the background. The result was a bit surprising as I got a bit of a halo effect when using the filter.

To me, the effects of this filter may be subtle or they may be more pronounced and that will depend on how you set up your shot and where the light source is. I found these filters to be a pleasant surprise. For me, there will be a little bit of a learning curve to determine when I might want to use these.

This is a nice quality filter set to add some interesting softening effects to your pictures.

I got this to use when making movies primarily to add some atmosphere and/or softening to the shot.

The metal feels nice and solid and has some ridges to grip them which is nice. I tested with the camera pointing into glare and with the glare behind me. I like the effect, for me the 1/8 and 1/4 are plenty, plus you could stack them if you really wanted to increase the effect.

It came with 2 sealed microfiber cleaning clothes, a nice touch.

If you are looking into the light the effect is pronounced and you get some nice haloing.

Overall a great filter set at a reasonable price. Especially if it is something you want available but will not use all the time.

Another great value from K&F, though I have to concede that this is my first such diffusion filter, so I can't offer comparisons to other brands. Regardless, I feel that these are solid and well made, and first impressions are that these are very good in terms of coatings at this price point.

Overall, I feel like these diffusion filters are more of a novelty and artistic item, so to me, it's less important to have the absolutely best optical performance possible. but nonetheless, I don't feel that they notably distort or discolor the image, beyond the obvious desired diffusion effect. Colors still seem to come through neutral and free of excessive glare and flaring.

Only dislike is that they come in a sort of generic plastic storage box that lets them slide around freely, particularly if you're only storing a single filter at a time. But I guess this is sort of minor, and I should probably invest in a dedicated filter sleeve.

I'm a photographer who shoots both digital and analog. Sometimes, I really want a moody look to my black and white photos that is hard to achieve (for me, anyway) with digital. These filters add just enough diffusion to soften skin, add just a touch of halation, and increase the moodiness of a fog-shrouded scene.

There are two different strengths in this package - 1/8 and 1/4. They are screwed together when you receive them and both are fitted into a small plastic container. They were put together pretty tightly, but were easy to separate with a pair of filter wrenches. Screwed into a lens, or into a good quality step up ring, they screwed on smoothly without binding, and were easy to removed even when screwed on firmly. These filters did not create any color cast.

The 1/8 strength filter's effects are very subtle, and the 1/4 strength provides more of the look that I'm after. You can stack these filters for even more diffusion, but that's probably not a great idea in harsh sunlight, as you're likely to get some flare caused by light bouncing back and forth between the filters.

I've been impressed by the overall quality and aggressive pricing strategy of K&F Concepts. Each time I've picked up one of their products, it has been better than my previous purchase. If you want to add some diffusion to your photos or videos, this set of filters should definitely be on your list of possibilities.

I bought this for the times when I want a softer look doing landscapes or long exposures when out shooting and this filter works amazingly well.

K&F Concepts has always made fantastic products, I have many of their filters as well as a couple of their tripods and their quality is top notch!

True to description.

love them, Great soft effect

Good value for money and quick delivery.
