The Canon 127mm Cross Screen 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 has a thread pitch of 0.75mm.
