Hoya 55mm Misty Spot Gradual Effect Filter

Hoya Misty-Spots are available in four types: Gradual, Breeze, Windmill, and Halo. They have a sharp central image with a pleasant blurring of the outer field. With Misty-spot Gradual, blurring appears to emanate from the center. With Misty-spot Breeze, there is a uni-directional streaky blurring of the background. With Misty-spot Windmill, blurring appears to swirl around the center, and with Misty-spot Halo, blur appears to radiate from a single point at the edge of the field.
