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.

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.
