JJC 77mm Variable Star Filter Kit Cross Screen Starburst Optical Glass

This JJC lens star filters kit (4 points, 6 points and 8 points) is designed to be used perpendicular to a point light source such as the sun, a light bulb, a candle or anything highly reflective.

Features:
* Creates a starburst effect from point light sources within an image, ideal for shooting night scenes, jewelry, wedding photography and more
* Starburst effect features four, six or eight primary diffraction spikes which extend from the light source
* Constructed from optical glass for clarity and color fidelity
* Features an aluminum-alloy frame for durability while remaining lightweight
* A rotation ring on the upper part of the frame is available to help you adjust the direction of the points of light 4, 6, or 8 when using
* Compatible with any lens with 77mm diameter filter thread; double threaded (77mm inner/male and 77mm outer/female) design allows attaching other 77mm accessories like lens caps or screw-in hoods.

Note: The best star effect occurs when the light source is against a darker background. With an 8 point filter, the many star lines may tend to overpower the rest of the image, so use it carefully. Generally, mid-range apertures or larger are sufficient to achieve a good star effect. Always test before critical situations.
