Sirui MS24L-B 24mm T1.2 L Mount Cine Lens

The Sirui Night Walker 24mm T1.2 S35 Cine Lens (MS24L-B) is designed for filmmakers who need to shoot in challenging lighting conditions without sacrificing image quality. The ultrafast T1.2 aperture gathers significantly more light than typical T2.0 or T2.8 cine lenses, allowing you to keep ISO values low and maintain clean, noise-free footage during golden hour, dusk, or interior scenes with available light. The optical formula — 12 elements in 11 groups — is engineered to deliver sharp, consistent results even wide open at T1.2, with well-controlled chromatic aberration and minimal focus breathing that would otherwise disrupt smooth rack focus pulls during a take.

Built with a robust aluminum cine housing, the lens weighs approximately 500g, making it one of the lightest fast-aperture cine lenses available. This low weight is a significant advantage for gimbal work, handheld shooting, and travel setups where every gram counts. The 270-degree focus ring rotation gives precise, repeatable focus control suited for professional follow focus systems, while the 12 rounded aperture blades create pleasing, smooth bokeh that keeps backgrounds beautifully diffused. The 67mm front filter thread accepts standard ND and mist filters commonly used in cinematic production. Mounted on an L-mount APS-C or S35 camera, the 24mm focal length translates to roughly a 34mm full-frame equivalent — a natural, versatile perspective well-suited to dialogue scenes, street filmmaking, and environmental storytelling.
