The K&F Concept filter set includes UV, circular polarizing and ND1000 filters, as well as a magnetic adapter ring. The UV filter reduces the bluish cast and protects the lens’s front element from dust and other particles. The circular polarizing filter rotates to reduce or eliminate reflections and glare, and to enhance the blue tone of the sky.

The ND1000 filter reduces exposure by 10 stops, allowing greater aperture control to reduce depth of field or slower shutter speeds for more pronounced motion blur. The filters are made of optical glass and feature a slim design to prevent vignetting on lenses with focal lengths of up to 16 mm. They also have 16 layers of multi-coating. The protective coating resists water, oil, stains, scratches and abrasions. The magnetic ring screws onto the lens thread and holds the filters in place magnetically for quick installation, swapping or removal.
