This digital high grade super neutral density filter from Marumi screws onto 49mm camera lenses to reduce light intake to just 1/500th of normal light levels, allowing you to leave the shutter open for longer without overexposing, even on a bright day. Create ethereal, smooth images that capture the quality of movement, even in a still photograph. Ideal for creating striking images of flowing water, dramatic skies, travelling light, moving traffic and anything else your imagination can conjure.The Marumi DHG Super ND500 is equivalent to 9 stop, and reduces the light entering the lens without adding a colour cast, retaining a neutral balance that won’t alter the original colour of the image. With a special water and oil repellent coating, this filter is perfect for shooting natural wonders such as geysers and waterfalls without splashes or beading water on the lens spoiling the final shot.Complete with satin finish to prevent internal reflection, this filter has an slim profile to avoid vignetting, knurling on the frame for ease of grip, and an ultra-low reflection rate so that you can be sure of a clean image without ghosting or flare in any lighting condition. The scratch-resistant coating helps to diminish the risk of small scratches and scuffs that can result in overexposed and blown out spots on an otherwise beautiful image. This high quality filter is made in Japan.
