The K&F CONCEPT 77mm Ultra-Thin Adjustable 4–8 Point Star Filter is a creative lens filter designed to transform bright light sources into customizable starburst effects.

The K&F CONCEPT 77mm Ultra-Thin Adjustable 4–8 Point Star Filter is a creative optical filter designed for photographers and videographers who want to add dramatic starburst effects to point light sources. It transforms bright highlights such as streetlights, reflections, candles, and LEDs into visually striking star-shaped flares, enhancing the artistic mood of night and low-light scenes.

A key feature of this filter is its adjustable star effect mechanism, allowing users to rotate the front element to switch seamlessly between 4-point and 8-point star patterns. This flexibility enables precise creative control, making it suitable for both subtle enhancement and bold cinematic styling depending on the shooting environment.

Constructed from high-quality optical glass with advanced 18-layer nano coating, the filter improves light transmission while reducing reflections, flare, and image degradation. This ensures that star effects remain clean, sharp, and visually appealing without compromising overall image clarity or color accuracy.

The ultra-thin aluminum alloy frame is designed to minimize vignetting on wide-angle lenses while providing durability and stability during use. Despite its robust build, the filter remains lightweight and travel-friendly, making it suitable for outdoor photography and on-location shooting.

This 77mm version is ideal for larger DSLR and mirrorless lenses commonly used in landscape, portrait, and cinematic video production, where enhanced lighting effects can significantly elevate visual storytelling.
