K&F Nano-B Series 77mm Center Field Split Diopter Filter

The K&F Nano-B Series Center Field Split Diopter Filter is a professional optical filter designed for creative photography and videography. It creates a unique split focus effect, allowing simultaneous sharp focus on foreground and background subjects while the center remains blurred. This effect adds depth and artistic flair to portraits, landscapes, and cinematic shots.

Advantages

High-definition optical glass with multi-layer nano coating ensures excellent light transmission and minimal reflections. The ultra-slim aluminum alloy frame prevents vignetting on wide-angle lenses. Rotatable design lets you adjust the split line angle for precise composition. Waterproof, oil-proof, and scratch-resistant coatings protect the filter and extend its lifespan.
