Lens Filter K&F Concept STAR Gwiazdka 2-in-1 55 mm (x4 & x8) – KF01.2328

The K&F Concept STAR Gwiazdka 2-in-1 55 mm lens filter is a screw-on creative filter designed for lenses with a 55 mm thread. This single optical accessory provides two selectable starburst intensities — x4 and x8 — producing controlled diffraction lines from bright point light sources. The filter is intended to enhance night scenes, cityscapes, stage lighting and specular highlights in portrait or product photography by adding symmetrical star effects without digital editing.

Advantages

The two-in-one design lets photographers switch between moderate and stronger star effects without changing filters, reducing kit weight and handling time. As a screw-on filter for 55 mm threads, it offers secure attachment and consistent alignment for repeatable results. Built to produce optical diffraction rather than software-based overlays, the filter maintains natural light rendering, preserves color balance and avoids introducing digital artifacts.

Suitable for

• Night photography and cityscape shots with streetlights and illuminated buildings
• Concerts, theater and stage lighting where point lights create highlights
• Portraits and beauty shots that use specular highlights for creative emphasis
• Product and jewelry photography to accentuate reflective points
• Creative and long-exposure photography exploring light effects

Key specifications

• Filter thread size: 55 mm (screw-on)
• Effect modes: x4 starburst and x8 starburst
• Optical principle: diffraction-based star effect
• Material: optical filter glass with metal filter ring (screw mount)
• Compatibility: fits lenses with 55 mm front thread

How to use

Screw the filter onto the front thread of a 55 mm lens until it is hand-tight; avoid over-tightening. Compose the shot so that bright point light sources (streetlights, specular reflections, small highlights) are present in the frame — the star effect is strongest on distinct, small bright points. Choose x4 for subtler star lines or x8 for more pronounced diffraction. Meter and focus with the filter attached when possible; if autofocus performance is affected, use manual focus. For long exposures or night scenes, use a tripod to ensure stability and repeatable star patterns.

Usage recommendations

Use the filter primarily with bright point sources and when you want an in-camera starburst effect without post-processing. Avoid using the filter with extremely wide apertures when critical sharpness is required across the frame; stop down slightly to improve overall image sharpness. Clean the filter surface with a soft microfiber cloth and appropriate lens cleaner to maintain clear star quality.
