K&F Starlight Glare Colorful Rainbow Flare Filter Nano-B MRC 58mm (SB9138)

The K&F Starlight Glare Colorful Rainbow Flare Filter Nano-B MRC 58mm creates multicolored flares and streaks by diffracting incoming light through a precision optical surface. Designed to screw onto lenses with a 58mm filter thread, this filter produces vivid rainbow highlights and linear streaks while preserving overall image clarity. A Nano-B surface treatment and Multi-Resistant Coating (MRC) improve scratch resistance, reduce reflections, and make the filter easier to clean, supporting use in creative portrait, night and concert photography as well as video production.

Advantages

This filter produces controlled, artistic colorful flares and streaks without requiring post-processing, enabling in-camera effects for creative shoots. The Nano-B treatment and MRC help maintain optical performance by resisting fingerprints, dust and minor abrasions while minimizing unwanted internal reflections. Its standard 58mm thread mount makes it compatible with a wide range of lenses, and the optical design preserves central sharpness so that color streaks accentuate rather than obscure subjects.

Suitable for

• Creative portrait photography with colorful rim and eye-catching highlights
• Night and urban photography featuring streetlights and neon signs
• Concerts, stage performances and live-event videography
• Artistic and experimental still-life and product shoots

Key specifications

• Filter type: Colorful rainbow flare / diffraction flare filter
• Mount: 58mm screw-in filter thread
• Coating: Nano-B surface treatment with Multi-Resistant Coating (MRC)
• Effects: Multicolored light streaks and linear rainbow flares
• Optical behavior: Preserves central image clarity while producing colored diffraction artifacts

How to use

Attach the filter to any lens with a matching 58mm filter thread by screwing it onto the front element until secure; avoid over-tightening. Compose and expose as you normally would, then introduce bright point or line light sources (streetlights, stage lights, backlight or specular reflections) into the frame to generate colorful streaks and flares. Adjust angle, distance and aperture to change the intensity and length of the streaks: smaller apertures tend to produce more defined streaks, while larger apertures yield softer effects. For video, keep movements steady or use controlled camera motion to maintain consistent flare behavior.

Usage recommendations

Use the filter to achieve in-camera color flares during creative shoots; test different light angles and apertures before important takes. Clean the coated surface gently with a microfiber cloth and appropriate cleaner to preserve the Nano-B and MRC treatments. When not in use, store the filter in a protective case to avoid scratches and dust.
