NiSi Cine Lens Aureus Prime 24mm T1.4 PL-Mount

NiSi Cine Lens Aureus Prime 24mm T1.4 PL-Mount – Fast T1.4 Aperture for Low-Light Cinematography

NiSi Aureus Prime 24mm T1.4 PL-Mount is a full-frame cine lens built for modern cinematography. It delivers a bright T1.4 aperture for low-light shooting and maintains image quality across the aperture range. The lens combines optical clarity, consistent mechanics, and practical features required for professional production work.

Key optical features

The lens is engineered for full-frame cameras and provides a 46mm image circle to ensure full-frame coverage without vignetting. Across the full aperture range from T1.4 to T22, the Aureus Prime maintains strong image quality, preserving fine detail and resolution from center to edge.

• Fast T1.4 aperture: Enables shooting in extreme low-light conditions while offering depth-of-field control and cinematic bokeh.
• Exceptional image quality across apertures: Designed to preserve detail and resolution from center to edge between T1.4 and T22.
• Minimal chromatic aberration: Advanced optical elements with ultra-low dispersion reduce chromatic aberration, distortion, and color fringing.
• Neutral and accurate color reproduction: The optical design aims to deliver true-to-life colors and a natural tonal range for consistent color matching across shots.
• Zero focus breathing: Near-elimination of focus breathing supports smooth, natural focus pulls and stable composition during pulls.

Focus, control and mechanics

The Aureus Prime offers cinematic control for manual focus and professional workflows. A long 300° focus rotation gives precise control for repeatable focus pulls. The focus scale comes set to feet by default and can be swapped to meters when preferred.

• 300° focus rotation: Provides precise, gradual manual focus control for demanding shooting scenarios.
• Interchangeable focus scale: Default scale in feet; can be swapped to meters with a tool (tool sold separately).
• Consistent series mechanics: The Aureus Prime series shares a uniform 90mm front diameter and consistent weight distribution, helping when swapping lenses on rigging, matte boxes, and follow-focus systems.

Build, compatibility and workflow

The lens uses durable, lightweight metal construction suited to a range of production environments. It integrates with PL-mount camera systems and supports common PL adapters and drop-in filter adapters used in cinema workflows.

• Durable metal construction: Precision-engineered metal build that supports handheld, gimbal, and drone applications while remaining robust.
• PL mount compatibility: Designed for PL-mount cameras; flange distance at infinity across the set ranges from 16.08mm to 19.92mm, ensuring integration with PL systems.
• Rear filter system: Built-in interchangeable rear filter system for quick use of ND, diffusion, or specialty filters without adding front-mounted filters.
• Adapter compatibility: Fully compatible with a wide range of PL adapters, including adapters with drop-in filter options.

Series consistency and pairing

The Aureus Prime line is optimized to pair with NiSi’s Athena Prime lenses. The series shares a similar optical character so filmmakers can mix and match lenses across a production without compromising image consistency.
