K&F STAR Gwiazdka 2‑in‑1 x4/x8 Star Filter for 77 mm Lenses KF01.2333

The K&F STAR Gwiazdka 2‑in‑1 x4/x8 Star Filter for 77 mm Lenses (model KF01.2333) is an optical screw-in filter designed to produce controllable starburst effects from point light sources. With an adjustable mechanism that selects between four-ray and eight-ray diffraction patterns, this accessory modifies specular highlights into defined streaks without relying on post-processing. The filter mounts on any lens with a 77 mm thread and is intended for creative and practical use in night, cityscape, portrait and event photography where highlight shaping is required.

Advantages

The filter offers two distinct star patterns in a single unit, allowing quick switching between subtle four‑ray and more pronounced eight‑ray effects. Its screw-mount design ensures secure and precise attachment to 77 mm lenses, maintaining optical alignment and ease of use. Because the effect is produced optically, photographers can capture final-look images in-camera, reducing the need for time-consuming digital editing. The construction is optimized to preserve image quality while adding defined diffraction streaks to point highlights.

Suitable for

• Night and cityscape photography to enhance lights and street scenes
• Portraits where controlled starbursts add creative highlights
• Event and concert photography to emphasize stage lights
• Product and still-life images requiring stylized specular highlights

Key specifications

• Filter type: 2‑in‑1 star diffraction filter with selectable 4‑ray and 8‑ray patterns
• Mount: screw-in design for 77 mm lens filter threads
• Effect: optical creation of starburst streaks from point light sources
• Compatibility: designed for lenses with 77 mm front thread diameter

How to use

Attach the filter to the front of a lens with a 77 mm thread by screwing it in until secure. Rotate or switch the filter element as indicated to select either the 4‑ray or 8‑ray star pattern. Frame and expose the scene as usual; the star effect will appear on bright point light sources such as street lamps, reflections and specular highlights. For sharper, more distinct streaks, use smaller apertures; for softer, subtler effects, open the aperture slightly. Check focus and exposure on the camera’s live view to confirm the desired star intensity before finalising the shot.

Usage recommendations

Use the 4‑ray setting for understated highlights and the 8‑ray setting when stronger starbursts are desired. Combine the filter with a tripod and smaller apertures for night scenes and long exposures to maintain image sharpness and consistent star shapes. Avoid using the filter in scenes where diffraction artifacts on broad light sources would reduce image clarity.
