The B+W 58mm Cross Screen 4X 684 Filter is a cross screen filter providing 4 reflected light points stemming from specular highlights within the image frame. When the filter is rotated in front of the lens, the points shift in direction but always reflect symmetrically. This effect is caused by thinly etched lines on one of the planes of the filter. Star effect filters are most effective when not used in combination with other filters.
This filter is constructed from optical-grade acrylic and features a brass filter ring for durability as well as jamming prevention.
