Blackmagic URSA Cine Mount EF

The Blackmagic URSA Cine EF Mount is a professional adapter that allows you to use high-end cinema and photography lenses on your URSA Cine camera. Designed to integrate easily with the camera body, this compact and interchangeable mount facilitates the seamless employment of Canon EF lenses, providing a rock-solid locking mechanism to ensure your glass remains perfectly stable during operation. By utilizing this mount, you can leverage a massive range of widely available optics, from affordable vintage primes to modern high-speed photography lenses.

To support an efficient digital workflow, the mount includes integrated electronic contact pins that enable full communication between the lens and the camera. This allows the camera to read and record vital lens metadata—such as iris, focus, and zoom settings—directly into your files, which is essential for accurate monitoring and post-production. Additionally, the mount supports active lens control, giving you the ability to adjust aperture and focus electronically through the camera's interface or compatible accessories.

Product Features in Detail

Extensive EF Lens Compatibility

The URSA Cine EF Mount allows you to tap into one of the most diverse lens ecosystems in the world. Whether you are using high-end EF cinema primes or widely available DSLR photography lenses, this mount provides the flexibility to choose the right aesthetic for your project, making it ideal for everything from documentaries to commercial productions.

Active Electronic Lens Control

Equipped with a sophisticated electronic interface, this mount provides active control over compatible EF lenses. This allows you to adjust the iris and focus directly from the camera’s touchscreen or via remote control demands, providing smooth and precise adjustments without needing to touch the lens barrel.

Automatic Metadata Population

The integrated contact pins allow the camera to automatically capture and record frame-by-frame metadata. Information such as the lens model, focal length, and aperture setting is saved directly into your Blackmagic RAW files, which is critical for maintaining consistency on set and streamlining visual effects workflows in post-production.

Secure Locking EF Interface

Unlike standard "twist-and-click" photography mounts, the URSA Cine EF Mount features a professional locking ring. This ensures that the lens is clamped firmly into place, eliminating the "play" or wobbling often associated with EF lenses, which is essential when using heavy cinema-style lenses or high-torque wireless follow-focus motors.

Compact, Interchangeable Design

As part of the URSA Cine’s modular mounting system, this adapter is designed to be easily swapped in the field. You can quickly transition from an EF setup to a PL or LPL configuration in minutes, ensuring your camera remains versatile and ready to adapt to whatever lens package the production requires.

Full-Frame Sensor Optimization

The mount is meticulously engineered to ensure that the URSA Cine’s large-format sensor is fully covered by the image circle of full-frame EF lenses. This allows you to utilize the camera's entire 12K sensor area, preserving the intended field of view and shallow depth of field of your favorite professional optics.
