Attaching and removing a PL lens
Cooke Lenses /i Technology Support
The optional Blackmagic Design PL mount available for URSA Broadcast and URSA Mini Pro
4.6K features four pins at the 12 o'clock position that are used to communicate with lenses
featuring Cooke’s /i Technology interface. The lenses that support this interface include lenses
from Canon, Cooke, Fujinon, Leica and Zeiss. This lets you record lens information in your clips’
metadata such as the lens model, focal length, aperture setting, focus distance and other lens
specific information.
The information that is recorded as metadata via Cooke's /i Technology interface can be very
helpful in post production and VFX. Knowing the lenses used in production and their precise
settings can be helpful in the event that the setup needs to be replicated at a later date.
This detailed information can also be utilised by powerful applications such as DaVinci Resolve
and Blackmagic Fusion for a wide variety of advanced functions. For example, the recorded
metadata can be used to simulate the specific lens in 3D space, or correct lens distortions.
PL Mount Servo Lenses
URSA Broadcast supports control of PL 35mm lenses with servo handgrips. When the lens is
plugged in to the 12-pin broadcast connector on the camera, URSA Broadcast will provide
power and control signals to your lens in the same way it does with B4 lenses. For more
information refer to the 'Using Servo Zoom Lenses' section in this manual.
