K&F Starlight Glare Colorful Rainbow Flare Nano-B MRC 77mm camera filter (SB9142)

The K&F Starlight Glare Colorful Rainbow Flare Nano-B MRC 77mm camera filter creates controlled, multicolored flare and star-like glare effects for creative photography. This screw-in optical filter attaches to lenses with a 77mm thread and modifies bright points of light, producing rainbow streaks, prismatic flares and radiating star patterns. It is intended for photographers who want to introduce intentional lens flare and chromatic highlights into portraits, night scenes, concert images and other artistic compositions while maintaining predictable framing and color behavior.

Advantages

This filter offers a simple, repeatable way to produce colorful flare effects without post-processing. Its Nano-B multi-resistant coating (MRC) reduces unwanted reflections and helps preserve contrast in non-flared areas. The screw-in 77mm design provides secure mounting and compatibility with a wide range of lenses that accept 77mm filters, allowing photographers to add creative light effects quickly in-camera. The optic is designed to distribute highlights into distinct rainbow streaks and star-like rays rather than diffuse bloom, giving greater control over the final look.

Suitable for

• Artistic portrait photography with controlled flare accents
• Night and cityscape scenes featuring streetlights and illuminated signs
• Concert and stage photography to enhance spotlights and colored lighting
• Creative commercial and social media imagery requiring distinctive light effects

Key specifications

How to use

Screw the filter onto the front thread of a lens that accepts 77mm filters. Frame your subject and identify light sources or specular highlights that you want to transform into colored streaks or star-like flares. Adjust composition, aperture and exposure to balance the flare with overall scene brightness: smaller apertures tend to produce more defined star rays while wider apertures emphasize bokeh and softer streaks. Move the camera or change the angle relative to the light source to vary the flare intensity and direction. Review images on the camera and fine-tune distance, framing and exposure until the desired effect is achieved.

Usage recommendations

Use the filter when you want visible, intentional flare as part of the image aesthetic; avoid when accurate, shadow-free rendering of highlights is required. Combine with moderate aperture settings for clear star rays, and test different light angles to control color dispersion. Store the filter in a protective case when not in use to keep coatings clean and scratch-free.
