Hoya Center Neutral Density ND - This filter combines two curved optics, one of which is neutral density and the other is clear. This gives the effect of a gradual fade towards the edges, with a difference of 1 stop from centre to edge.
Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting.
