K&F makes quality photographic equipment at a modest price. I have been happy with their products in the past and this filter is no different. It comes in a sturdy box and plastic lens holder and three lens cleaning tissues in hermetically sealed envelopes. It screwed easily onto my broken Sony 24-105G lens, it also attached to the UV filter. It feels well made and has a knurled edge for an easy grip. The effect is pleasant and slightly painterly. I don't feel comfortable uploading headshots of people, but it softens the highlights in portraits in a nice subtle way, especially with strong edge lighting. 1/8 is very subtle. I would like to add that a blooming light source looks good most of the time. However, if you have a subject in front of the bloom, it can obscure the subject. You can see that a bit in my photo with the house light behind the rock. The bloom looks cool but if that was a model it would block her. I often add a glow or the variant called the Orton effect in the post. This black diffusion filter is cleaner in that it only affects the highlights. I have the filter at one when it affects only the highlights. I have the filter at one when it affects only the highlights. I have the filter at one
