The K&F Concept filter set includes a UV filter, a circular polarizing filter, and an ND1000 filter, with a magnetic mounting system. The UV filter reduces bluish color casts and protects the lens’s front optical element from particles. The circular polarizing filter rotates to reduce or eliminate reflections and glare, as well as enhance the blue tones of the sky.

The ND1000 filter reduces exposure across the entire image by 10 stops, allowing finer aperture control to reduce depth of field or longer shutter speeds for increased motion blur. The filters are made of optical glass and have a slim design to prevent vignetting on wide-angle lenses with focal lengths down to 16 mm. The magnetic ring screws onto the lens thread and allows the filters to be quickly attached, changed, or removed.
