K&F STAR Gwiazdka 2in1 x4 and x8 Star Filter for 49 mm lenses KF01.2326

The K&F STAR Gwiazdka 2in1 x4 and x8 Star Filter for 49 mm lenses is a screw-in creative filter that produces multi-point star flares from bright point light sources. It offers two selectable star-effect intensities—x4 and x8—allowing photographers to emphasize highlights in night scenes, cityscapes, holiday light compositions, and studio or on-location portrait highlights. The filter is designed for lenses with a 49 mm front thread and secures by screwing onto the lens for reliable mounting and quick interchange between effects.

Advantages

The two-in-one design integrates both x4 and x8 star patterns in a single screw-in unit, eliminating the need to carry separate filters for different flare intensities. Its metal thread and compact profile maintain stable attachment and preserve access to the lens barrel and focussing controls. The optical surface is engineered to create pronounced, evenly distributed star rays from point light sources while keeping the overall image sharpness and color balance largely unaffected. Simple mechanical operation makes it suitable for on-the-fly creative adjustments.

Suitable for

• Night and low-light cityscapes with streetlights and reflections
• Holiday and decorative lighting photography
• Portraits where specular highlights are present (hair lights, catchlights)
• Architectural shots featuring point lights or illuminated facades
• Creative long-exposure and event photography to emphasize bright points

Key specifications

• Filter type: star (cross) effect filter with two intensities
• Available star patterns: 4-point and 8-point
• Mount: screw-in for 49 mm front threads
• Material: metal threaded ring with optical filter element
• Optical characteristics: produces multi-point diffraction spikes from bright light sources
• Form factor: slim profile suitable for compact mounting without significant vignetting on standard focal lengths

How to use

Screw the filter onto the lens front thread until it is securely seated. To select the desired star effect, rotate or align the filter elements as indicated by its design (x4 or x8 setting); the product is engineered for quick swapping between the two effects. Compose your shot with bright point light sources in the frame—streetlights, city highlights, reflections, or specular highlights on subjects—and adjust exposure settings to account for the intensified highlights. Use a tripod for low-light, long-exposure scenes to maintain sharpness while capturing star flares.

Izmantošanas ieteikumi

For best results keep the light source small and bright relative to the frame; avoid overexposed highlights that can wash out the star effect. Clean the filter surface before shooting to prevent unwanted flare from dust or smudges. When combining with other filters, check for additional reflections or vignetting and use a hood or flagging to control stray light.
