Sigma 50mm T1.5 FF High Speed Prime

Standard Reference Cinematic Prime

The Sigma 50mm T1.5 FF Cine Prime is a standard reference focal length in the FF High Speed Prime lineup, designed to replicate a natural human perspective with cinematic depth and clarity. It is one of the most commonly used lenses in narrative filmmaking, commercials, and studio productions.

The T1.5 aperture delivers strong low-light capability and enables shallow depth of field with smooth bokeh, making it ideal for portrait-oriented cinematography and controlled lighting environments.

Optically, the lens offers high sharpness, natural color rendering, and well-controlled distortion. It maintains consistent performance across the frame and matches seamlessly with the rest of the Sigma cine lineup.

Focus breathing is minimized for stable composition during focus pulls, supporting precise narrative work. The lens is optimized for modern high-resolution cinema sensors up to 8K.

Mechanically, the cine housing features standardized 0.8 MOD gears, long focus throw for precision work, and durable all-metal construction suitable for demanding production environments.
