Filter K&F STAR Gwiazdka 2in1 x4 and x8 for 67 mm lenses (KF01.2331)

The K&F STAR Gwiazdka 2in1 x4 and x8 for 67 mm lenses is a screw-on star effect filter designed to add controlled star-shaped diffraction to bright light sources in photographs. Compatible with lenses that accept 67 mm screw-in filters, this filter provides two selectable diffraction patterns — a four-point (x4) and an eight-point (x8) star — to emphasize highlights such as streetlights, reflections and festive lighting. Its simple mechanical selector lets you switch between patterns without removing the filter, making it suitable for creative stills and long-exposure photography.

Advantages

This filter offers two distinct star patterns in a single slim screw-on unit, reducing the need to carry multiple filters. The metal screw mount secures the filter to standard 67 mm threads and maintains optical alignment. The selectable mechanism enables quick changes between x4 and x8 diffraction effects, providing flexibility while shooting. The design preserves framing and exposure workflows typical for screw-in filters and is compatible with common photographic lenses that accept 67 mm accessories.

Suitable for

• Night photography of cityscapes and streets with point light sources
• Holiday and decorative lighting to add creative star effects
• Reflective highlights on water, glass or metallic surfaces
• Long-exposure scenes where star diffraction enhances light trails

Key specifications

• Filter type: screw-on star diffraction filter with selectable patterns
• Star patterns: four-point (x4) and eight-point (x8), switchable
• Mount diameter: fits 67 mm lens filter threads
• Construction: slim profile with metal screw mount and selectable mechanism

How to use

Attach the filter to a lens with a 67 mm filter thread by screwing it into place until snug; avoid overtightening. Compose your scene and choose the desired star pattern using the filter's selector. For stronger star effects, include bright point light sources in the frame such as streetlights, holiday lights or reflections. When using long exposures, confirm focus and exposure before engaging the effect, as diffraction can slightly alter perceived sharpness. Remove the filter when no star effect is needed to return to normal imaging.

Usage recommendations

Use the x4 pattern for subtle enhancement and the x8 pattern when more pronounced starbursts are required. Select lenses with moderate to small apertures (higher f-numbers) to increase the visibility of diffraction spikes. Keep the filter clean and free of fingerprints to avoid flares and loss of contrast, and store it in a protective case when not in use.
