The Magnetic ND1000 Filter Plus+ brings ease to your creative flow with a convenient, stackable, magnetic system. These layers also provide a higher maximum light transmission and a more consistent transmission curve for truer light reduction. The Plus+ range features 20 layers of nanocoating, providing easier cleaning and better protection against water, oil, and scratches. With less light entering your camera, you can also use wider apertures in bright light for a beautiful shallower depth of field effect without overexposing images. The Urth 77mm Magnetic ND1000 (10 Stop) Lens Filter Plus+ easily snaps in place, providing a fixed 10 f-stop light reduction for better control with long exposure and motion blur techniques in bright light.
