K&F Concept 77MM Centerfield Split Diopter Filter

The K&F Concept 77mm Centerfield Split Diopter Filter (Nano-B Series) is a creative special-effect filter designed to blur the foreground and edges while keeping the center sharp, producing depth, layering, and striking visual effects ideal for portraits, landscapes, and artistic photography.

The K&F Concept 77mm Centerfield Split Diopter Filter from the Nano-B Series is a premium special-effects accessory crafted for photographers seeking unique visual results. Featuring a center-sharp, edge-blur split diopter design, it adds soft refraction and atmospheric blur to the perimeter of your frame while maintaining crisp detail at the focal point. This effect enhances depth and composition, making it perfect for creative portraiture, dreamy landscapes, and artistic conceptual work. Built with high-quality Japanese AGC optical glass, the filter ensures high light transmission, excellent color accuracy, and image clarity. Its adjustable rotating frame allows you to fine-tune the effect to match changing environments and artistic needs. The sandblasted, oxidized frame minimizes stray light for optimal performance. Included with the filter is a premium microfiber cleaning cloth, vacuum-packed, lint-free, and safe for delicate optics.
