The Star 4X is the popular artistic Hoya filter designed to create a dramatic 4-point cross-flare effect. Available sizes (mm): 49, 52, 55, 58, 62, 67, 72, 77, 82.

The Hoya Star 4X filter produces a 4-point flare on light sources and is ideal for capturing night lighting, reflections on water surfaces, light filtering through leaves, jewelry photography, and other scenes featuring tiny light sources. Star filters create dramatic multi-point light reflections or light rays, also known as the "star effect," which highlight bright or intense point light sources.

Star filters come in three different variants: Star 4X, Star 6X, and Star 8X, each producing 4, 6, or 8 light rays emanating from the light source. Hoya star filters have structures etched into the surface of the high-quality optical glass of the filter to create the star effect. Each filter, Star 4X, Star 6X, and Star 8X, has different line patterns etched into the glass to generate the number of light rays for that filter.

The star filter creates a beautiful and romantic effect by emitting multiple light rays from a point light source or a bright object in the image. The appearance of the rays can vary depending on the aperture setting, size, intensity of the light source, and distance from the camera. Find the best angle for the star effect according to your personal preferences by rotating the filter frame. When shooting a video, rotate the frame to achieve dynamic and rhythmic movements of the rays.
