I am selling this item because I no longer have a use for it. R-Cross Screen Standard 4-line cross effect This filter adds a 4-line light accent to photos of sparkling water surfaces, sunlight filtering through leaves, illuminations, and accessories. By rotating the filter frame, the light streaks also rotate, allowing you to find your preferred orientation for shooting. During video shooting, rotating the filter frame creates beautiful flares that move rhythmically. This filter is suitable for shooting with lenses of 50mm or longer focal length, at apertures close to wide open. *With wide-angle lenses, the lines of the filter may be broken if you stop down to F5.6 or higher, so please use it near the lens's maximum aperture. Also, because the rotating frame is thick, vignetting may occur with wide-angle lenses.
