K&F Nano-B Center Field Split Diopter Filter 58mm +0.5 Diopter

The K&F Nano-B Center Field Split Diopter Filter is a specialized creative filter designed for photographers who want to achieve unique focus effects. With a 58mm diameter and +0.5 diopter strength, this filter creates a sharp central area while blurring the foreground and background, perfect for portrait, macro, and artistic photography.

Advantages
