The Magnetic ND1000 Filter Plus+ brings ease to your creative flow with a convenient stackable, magnetic system. It features 20 layers of nano-coating providing easier cleaning and better protection against water, oil, and scratches. These layers also provide a higher maximum light transmission and a more consistent transmission curve for truer light reduction. 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 58mm Magnetic ND1000 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.
