Shoot even in minimal light
The extreme lens aperture of the SIRUI Vision Prime 1 T1.4 lens allows shooting in even the minimum available light, giving filmmakers full control over depth of field. The lens produces soft, natural bokeh and contributes to a distinct cinematic image character without harsh transitions. Thanks to the high microcontrast and consistent drawing, the image is legible, plastic and looks professional even with the aperture open.

With minimal distortion
The optical design of the SIRUI Vision Prime 1, consisting of 14 elements in 11 groups, uses aspherical elements and low dispersion glass to minimize distortion, chromatic aberration and provide high resolution across the entire image field. Advanced multi-layer nano coatings effectively suppress glare and enhance contrast, which is especially useful when working in backlight or difficult lighting conditions.

With a naturally blurred background
The SIRUI Vision Prime 1 lens is a full-featured cine tool with manual focus, gear rings and a long 270° focus range for maximum precision when refocusing. Minimized focus breathing ensures smooth focus changes without unwanted compositional changes, which is crucial for professional film production. The 12-labeled aperture contributes to a smooth and natural background blur.

With wide compatibility
The Vision Prime 1 series is designed with uniformity in mind. All lenses have the same design, similar dimensions and identical position of controls, making it much easier to change lenses on set without the need to rebuild rigs or follow focus systems. The interchangeable bayonet ensures wide compatibility with Sony, Nikon, Canon and Leica cameras.
