This is a diffusion filter that adds just a subtle amount of haze to you're shots. It also exhibits a slight grey tint. I would approximate 5%. This product is compatible with the following cameras Fujifilm X100/X100F/X100S/X100T/X100V/X100VI (Nano-X Series).

The whole premise of this filter is to add subtle haze and bloom to film and video. This helps to soften light and overall skin. This helps in reducing wrinkles fine lines and pores. Adding a somewhat dream like effect. There are many grades ( percentage ) of haze you can add with various other filters in this lineup. From subtle such as this one to vary bloomed and hazy.

I have had the pleasure of reviewing K&H products in the past and they've always shown great attention to detail and superb craftsmanship. Their lens glass has always been superb with edge to edge sharpness and good optic properties.

Things to consider:
As you can see adding additional glass may result in reflections and extra light flares. This is common and is part of the trade off when using certain types of lens add-ons.

Final thoughts:
This is a good tool to have in you're kit. On those special occasions where you need extra mood. Perfect for weddings, child photography, dream sequences in film and many more concepts. With great build quality and a well designed carrying case. This product might be what you've been looking for.
