The LDS Ultra Prime 85mm T1.9 Lens creates a sharp image consistent with the other ARRI lenses in color and contrast, covers Super 35mm imagers, and integrates encoders and electronic contacts into its ARRI PL-mount. It is an internal focus lens for precise focusing, and it features fully floating lens elements that improve lens performance in close-ups. This lens is marked in feet.
In addition to using the same optical elements as ARRI’s Ultra Prime series, internal encoders are built into the LDS Ultra Prime series to allow the lenses to communicate with the camera and provide metadata for use in post. Each lens maintains uniform and constant position of lens scales with similar gear positions.
