K&F Concept Blue Streak Filter 4″x5.65″ (KF01.2453) Overview

The K&F Concept Square Blue Streak Filter 4″ x 5.65″ is designed for cinematic visual effects and professional video production. Engineered to mount directly into a matte box system, it is fully compatible with Tilta, SmallRig, mini matte boxes, filter frames, and other standard 4″ x 5.65″ matte box setups, making it a versatile choice for filmmakers.

This blue streak filter creates a cool, brushed cinematic look, adding subtle blue transparent streaks across highlights. It enhances creative visuals by producing stylish blur, gradient, and distortion effects, ideal for achieving modern cinematic lighting and dramatic scenes.

With 0.2% ultra-low reflectivity, the filter effectively reduces lens reflections, flare, and halo artifacts, delivering clearer images with higher contrast and rich details. It is perfectly suited for 4K and 8K high-resolution video recording.

Constructed from premium Japanese AGC optical glass, the filter features a 28-layer nano-coating on both sides to minimize glare and reflections. The coating also provides scratch resistance, water repellency, and oil resistance, ensuring durability and consistent performance in demanding shooting environments.

For safe storage and transport, the package includes a protective leather pouch lined with soft sponge, keeping the filter well-protected against impact and damage.
