This Rear Lens ND Filter Kit from Haida contains four tempered glass neutral density filters that mount in the rear of the Nikon Z 14-24mm f/2.8 S lens using the included rear adapter ring. Each filter is multicoated for optimal light transmission and darkens the entire image area. Applying neutral density makes it possible to shoot at longer shutter speeds to add blur and movement, or at wider apertures for more control over depth of field. This is useful when shooting landscapes in bright sunlight.
