SIRUI Vision Prime 1 50mm T1.4 FF Cine Lens Overview
Capture sharp, cinematic medium and close-up shots with the SIRUI VP-1 Vision Prime 50mm T1.4 Full-Frame Cine Lens. Compatible with full-frame mirrorless cameras, the lens sports an expansive 46mm image circle, ensuring edge-to-edge sharpness and coverage without vignetting, even when shooting open gate. Its ultrafast T1.4 aperture excels in low-light conditions, and features an 18-blade design that creates a beautifully shallow depth of field with smooth, cinematic bokeh. All VP-1 series lenses have native Sony E-mounts and come with user-changeable mount adapters for Canon RF, Nikon Z, and Leica L-mount cameras, allowing seamless compatibility across multiple camera systems.
Built with aspherical lens elements and high-refractive index (HRI) glass, this lens 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. Its multi-layer nano coating provides superior flare suppression, while its 270° focus throw with stepless focus control ensures 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 lens line ideal for cinematographers seeking premium optics with maximum flexibility.
