Lens Filter Set K&F 3-in-1 Star Filters (Star X4, X6, X8) 77mm

K&F 3-in-1 Star Filters set for 77mm lenses includes three interchangeable screw-on filters: Star X4, Star X6 and Star X8. Each filter creates multi-point starburst effects from bright light sources and attaches to any lens with a 77mm filter thread. The set is compact and designed for quick swapping, allowing photographers to vary the intensity and number of star points for landscape, night and creative photography without additional accessories.

Advantages

The filters produce consistent, well-defined starbursts by using etched lines in the optical glass to diffract point light sources. Being screw-on 77mm filters, they are compatible with a wide range of lenses and are simple to fit and remove. The three-filter combination gives flexibility to choose between four-, six- or eight-point star effects, enabling varied creative outcomes without bulky rigs. The compact metal frame and slim profile minimise vignetting on most full-frame and APS-C lenses when used within normal focal length ranges.

Suitable for

• Night photography with streetlights, cityscapes and starry skies
• Landscape and sunset shots with specular highlights
• Architectural and city-scene photography featuring bright point lights
• Creative and portrait shoots where controlled star effects are desired

How to use

Screw the chosen star filter onto the front of any lens with a 77mm thread until secure. Compose the scene and expose for the overall image; if needed, stop down the aperture to enhance star sharpness and define the number of rays. Use the X4 for subtler four-point stars, X6 for moderate six-point effects and X8 for pronounced eight-point bursts. Swap filters by unscrewing one and fitting another; handle the glass edges carefully to avoid fingerprints and dust.

Usage recommendations

For best results, use the filters with point-like light sources such as street lamps, specular reflections or distant suns. Reducing aperture (higher f-number) increases star definition. Avoid strong obstructions close to the lens edge that may alter the star shape, and store filters in a protective pouch when not in use to preserve coatings and glass clarity.
