Schneider makes both soft-edge(SE) and hard-edge(HE) Graduated Color filters. Typically, soft-edge filters are used with wide to medium-angle lenses because these lenses have greater depth of field. Hard-edge filters are preferred for use with telephoto lenses or for bold transitions.156.67Schneider Opticsadd-to-cart
