Filter K&F Blue Streak Anamorphic Nano-X MRC 72mm (SB7874)

The Filter K&F Blue Streak Anamorphic Nano-X MRC 72mm is an optical accessory for photographic and cinematic lenses with a 72mm filter thread. It combines anamorphic image characteristics with surface treatments designed to minimise stray reflections and simplify cleaning. The filter is intended to produce anamorphic flare and oval bokeh effects while offering a degree of physical protection to the front element of the lens during shoots.

Advantages

The Multi-Resistant Coating (MRC) reduces ghosting and unwanted reflections across the visible spectrum, improving contrast when shooting in challenging light. The Nano‑X surface treatment makes the filter easier to clean and more resistant to fingerprints, oil and moisture. The anamorphic design produces horizontal flare and stretched highlights typical of anamorphic optics without requiring an expensive anamorphic lens, enabling filmmakers and photographers to achieve cinematic characteristics with standard glass.

Suitable for

• Filmmakers seeking anamorphic flare and cinematic highlights
• Photographers pursuing creative bokeh and stretched highlights
• On‑location shoots where front lens protection and easy cleaning are important
• Hybrid photo/video setups using lenses with a 72mm thread

Key specifications

• Thread size: 72mm
• Filter type: Anamorphic effect glass
• Coating: Multi‑Resistant Coating (MRC)
• Surface treatment: Nano‑X hydrophobic and oleophobic layer
• Primary function: Create anamorphic flare and protect front lens element

How to use

Screw the filter onto the front thread of a compatible lens (72mm). Compose and expose as usual; the optical treatment will introduce anisotropic flares and horizontally stretched highlights characteristic of anamorphic imaging. For minimal impact on image quality, use the filter with lenses that have minimal vignetting at the chosen focal length and aperture. Remove the filter when maximum sharpness or the original lens character is required.

Usage recommendations

Clean the filter with a soft microfiber cloth and approved lens cleaner to preserve the Nano‑X layer. When shooting strong direct light sources, adjust composition and angle to control the intensity and direction of anamorphic flare. Store the filter in a protective case when not in use to avoid scratches and contamination.
