The Blackmagic Design URSA Cine Mount HC is a professional lens mount adapter designed to enable the use of Heavy Duty (HD) and Large Format (LF) PL mount cinema lenses on URSA Mini Pro and URSA Broadcast G2 cameras. It serves as a critical interface, providing a secure, precise, and robust connection between the camera's native lens mount and high-end cinema lenses commonly used in feature film, commercial, and high-end broadcast production. The mount is engineered to maintain accurate flange focal distance, ensuring lenses focus to infinity and retain their optical performance when adapted to the URSA camera system.

Constructed from high-grade aluminum alloy with stainless steel components, the URSA Cine Mount HC is built for durability and reliability on demanding sets. It features a positive locking mechanism that securely engages the lens, preventing rotation or movement during operation—a crucial safety feature when using heavy, expensive cinema glass. The mount includes integrated electronic contacts that support lens data communication for models that transmit metadata, allowing information such as focal length and T-stop to be recorded alongside the video footage.

The adapter is designed for straightforward installation, typically requiring no tools or shimming for proper alignment. Its design maintains compatibility with the camera's internal ND filters and other optical systems. By providing a professional-grade PL mount solution, the URSA Cine Mount HC significantly expands the creative lens options available to URSA camera operators, allowing them to leverage the unique optical characteristics of a vast library of cinema primes and zooms for superior image quality and creative control.
