The Cavision 3 x 3" 8-Point Star Filter is a cross screen filter providing 8 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 the surface of the filter. Star effect filters are most effective when not used in combination with other filters.
This filter is constructed from optical glass to maintain high image quality and measures 3 x 3" / 76.2 x 76.2mm.
