Built with aspherical lens elements and high-refractive index (HRI) glass, this 3-lens kit offers outstanding optical performance in a compact, lightweight package, minimizing chromatic aberration, distortion, and focus breathing to achieve a truly cinematic aesthetic that meets the demands of 8K capture. Each lens has a multilayer nano coating to provide superior flare suppression and a 270° focus throw with stepless focus control to ensure precise, smooth focusing. The uniform design across the Sirui VP-1 Vision Prime series allows filmmakers to switch between focal lengths without needing to reposition accessories, making this kit ideal for cinematographers seeking premium optics with maximum flexibility. A waterproof, shockproof hard case with custom cutouts is included for added protection and convenience during transportation or storage.
