Urth 40.5mm ND16 (4 Stop) Lens Filter (Plus+)

Overview of the Urth ND16 4-stop Lens Filter Plus+ (40.5mm) The Urth ND16 4-stop Lens Filter Plus+ provides a fixed 4 f-stop light reduction for better control with long exposure and depth of field techniques in low light. With less light entering your camera, you can also use wider apertures in low light for a beautiful shallower depth of field effect without overexposing images. Cinematographers can use the ND16 Filter Plus+ to create more cinematic effects in low light without losing quality or overexposing the shot. The Plus+ range 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.
