KF Concept Filtro dióptrico de campo dividido central Nano-B de 82mm +0.5

On a film set, a cinematographer needs to keep a foreground subject and a distant background in sharp focus simultaneously. The KF Concept 82mm Center Field Split Diopter Filter makes this possible by placing a +0.5 diopter lens over half the frame, while the other half remains clear. This rotatable, ultra-slim filter lets you position the split along any axis, giving you precise control over the focal plane. Ideal for creative photography and videography, it opens up new possibilities for storytelling and visual effects.

Why choose it

The Nano-B coating ensures durability and easy cleaning, while the high-quality optical glass maintains image clarity.

The slim frame minimizes vignetting, even on wide-angle lenses.

Good to know

The split diopter effect is most pronounced at wider apertures. For best results, use a lens with manual focus and stop down slightly to balance the two focal planes. The filter comes with a protective case for safe storage and transport.
