The K&F Concept Variable C-Series ND Filter (77mm) is a versatile tool designed for photographers and videographers who need precise light control in changing conditions. Offering adjustable neutral density from ND2 to ND400, this filter allows you to reduce light intake by 1 to 8.6 stops without affecting color accuracy. Ideal for long-exposure photography, cinematic video, and creative depth-of-field control, it enables smooth motion blur in waterfalls, streams, clouds, and busy urban scenes.
Its blue multi-coated optical glass minimizes reflections and ghosting while maintaining sharp image quality. The slim aluminum frame helps prevent vignetting, even on wide-angle lenses, making it a reliable companion for landscape, travel, and outdoor shooting.
