Hybrid Compact Servo Zoom Lenses
Recently, a new category of lenses known as ‘compact-servo’ zoom lenses have been
introduced. These have some of the functionality of B4 and PL servo zoom lenses but use
an EF mount. The zoom rocker for these lenses can be powered through the lens mount from
URSA Broadcast G2 and information such as lens name, iris, focus and zoom position values
are allable to be read and recorded by URSA Broadcast G2’s lens metadata system.
Electronic control of the focus, iris and zoom is available with these lenses. When connected
toa switcher, these can also be controlled remotely via ATEMSoftware Control. If you are
operating in a live broadcast or studio environment, use of these lenses with Blackmagic Zoom
and Focus Demands is possible provided the iris switch on the barrel of the lens is set to ‘A’,
the focus switch is set to ‘AF’, and the zoom servo switch is set to ‘servo’.
Lenses in this range include:
Canon CN-E 18-80mm T4.4 Compact-servo
Canon CN-E 70-200mm T4.4 Compact-servo
Storage Media
Your Blackmagic URSA Broadcast G2 uses standard SD cards, faster UHS-II SD cards or
CFast2.0 cards to record video.
Using the rear USB-C 3.2 Gen 2x1 port, you can connect high speed flash disks or high
capacity solid state drives. You can also record to SSDs using the optional Blackmagic URSA
Mini Recorder. For more information on connecting URSA Mini Recorder to your camera, refer
to the ‘URSA Mini Recorder’ section later in this manual.
Important Notes About Media Speeds
Write and read speeds published by recording media manufacturers are often based
on peak speeds for small files such as still images, and may not accurately reflect write
speeds for a continuous stream of high speed video.
Forreliable recording with your chosen frame rates, use only the cards recommended
by Blackmagic Design.
CFast Cards
CFast 2.0 cards are capable of supporting very high data rates, so are perfect for recording
HDand 4K video at high frame rates. Refer to the record duration table in the ‘recording’
section for details on the maximum frame rates that can be recorded in each format.
It’s important to note that while CFast 2.0 cards are generally high speed cards, some cards
have slower write speeds compared to read speeds, and maximum data rates can differ
between models. For reliable recording with your chosen frame rates, use only the cards
recommended by Blackmagic Design.
