Blackmagic Design URSA Mini Pro PL Mount

Blackmagic Design URSA Mini Pro PL Mount

The Blackmagic Design URSA Mini Pro PL Mount is a high-precision, interchangeable lens mount that allows you to use professional cinema glass on your URSA Mini Pro (4.6K, G2, or 12K). While many URSA models ship with an EF mount as standard, this kit provides everything needed to swap to the industry-standard ARRI PL (Positive Lock) system.

In 2026, this remains a critical accessory for DPs who need to utilize high-end vintage or modern cine primes and zooms that require a more robust, mechanical locking interface than photographic mounts can provide.

Core Functionality

• Cooke /i Technology Support: The mount features integrated electronic pins that communicate with compatible PL lenses. This automatically captures and records metadata—such as lens name, focal length, aperture, and focus distance—directly into your Blackmagic RAW files.

• Precision Flange Adjustment: Because cinema lenses have extremely tight tolerances, the kit includes a Shim Kit. This allows you to precisely adjust the flange focal distance (the distance between the lens and the sensor) to ensure that your lens's focus marks remain 100% accurate.

• Superior Strength: The PL mount is made from titanium and stainless steel, designed to support the weight of heavy cinema zoom lenses without the "flex" often found in smaller mount types.

Installation & Design

• User-Interchangeable: You do not need to send the camera to a service center. The mount is secured by four screws on the front of the URSA Mini Pro chassis.

• Internal Baffle: The kit includes a specialized light baffle that fits behind the mount to prevent internal reflections and ensure maximum contrast, particularly when shooting at high resolutions like 12K.

• Storage Case: Comes with a molded, protective case to safely store your original EF mount (or other spare mounts) when they are not in use.

Operational Insight

In 2026, the PL mount is increasingly popular for URSA users who are moving into Virtual Production (Volume) work. The ability to pass frame-accurate lens metadata (via /i Technology) to Unreal Engine or other real-time renderers is essential for matching virtual backgrounds with live-action lens characteristics.

Pro Tip: Always use the included Baffle Tool during installation. Skipping the baffle can lead to "sensor flare" or reduced contrast in high-key lighting situations, as the internal reflections aren't being properly masked.
