Description
NiSi AUREUS PRIME 50mm T1.4 Full Frame Cinema Lens ( PL Mount )
The ultra-fast T1.4 aperture enables filmmakers to shoot in extreme low-light conditions while maintaining high image quality, rich contrast, and excellent depth of field control for beautiful cinematic bokeh. Designed for full-frame cinema cameras, these lenses ensure edge-to-edge sharpness without vignetting, delivering professional-grade clarity and detail in every frame. The near-elimination of focus breathing ensures that focus pulls are smooth and natural, with no noticeable shifts in composition—perfect for professional cinematographers looking for seamless transitions. Advanced optical engineering with ultra-low dispersion elements minimizes chromatic aberration, distortion, and color fringing, preserving true-to-life colors and crisp details even at the widest apertures. A long 300° focus throw provides cinematographers with precise manual focus control, ensuring smooth and accurate focus pulls for demanding shooting scenarios. The entire lens set features a uniform front diameter of 90mm and consistent weight distribution ( 1300g per lens ), allowing seamless compatibility with matte boxes, follow focus systems, and rigging setups. Flange distance at infinity ranges from 16.08mm to 19.92mm across the set, ensuring seamless integration with all PL-mount cameras. Fully compatible with a wide range of PL adapters, including those with drop-in filter options, expanding creative flexibility. Designed to deliver true-to-life colors with a natural tonal range, the lenses ensure seamless color matching across different shots, making them ideal for professional productions requiring uniform color consistency. Crafted from precision-engineered metal, the robust yet lightweight design makes these lenses ideal for handheld, gimbal, and drone applications without compromising durability. The built-in rear filter system allows for quick customization with ND, diffusion, or specialty filters, enabling filmmakers to achieve their desired look without requiring additional front-mounted filters. The focus scale is set up in feet by default but can be easily swapped to meters using a tool ( sold separately ), allowing cinematographers to work with their preferred measurement system for precise focus adjustments. Designed to pair seamlessly with NiSi’s Athena Prime lenses, the Aureus Prime series shares a similar optical character, allowing filmmakers to mix and match without compromising image quality or consistency across a production. The NiSi Aureus Prime Kit includes five meticulously matched focal lengths—18mm, 24mm, 35mm, 50mm and 85mm.
