Blackmagic Design URSA Mini Pro 12K (PL) - Manual (Page 144)

B4 Lenses with full servo control for focus, iris and zoom include:
‚ Fujinon B4 lens models with HA, ZA and UA prefixes in their name and the letters
RD or ZD in the suffix.
‚ Canon B4 lens models with HJ, KJ..ex and CJ prefixes in their name and the
letters IASE or IASD in the suffix.
Lenses that also have motorized focus control can even utilize the ‘focus’ button on your
URSA Mini to activate auto focus, and focus can be controlled remotely by an ATEM switcher
via ATEM Software Control.
Once you have attached a B4 lens, set the resolution to 2K 16:9 or lower, and ‘window sensor’
to ‘on’ in the ‘record’ tab of the dashboard. It is important to use these settings to prevent
vignetting of the image, as B4 lenses do not cover the super 35mm image circle.

studio environment on all of the PL and B4 servo zoom lenses listed above.
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 are able to be powered through the lens mount
from URSA Mini EF and URSA Mini Pro and information such as lens name, iris, focus and zoom
position values are all able to be read and recorded by URSA Mini’s lens metadata system.
Electronic control of the focus, iris and zoom is available with these lenses on URSA Mini and
URSA Mini Pro. When connected to a switcher, these can also be controlled remotely via
ATEM Software Control. If you are operating in a live broadcast or studio environment, use of
Canon digital focus and zoom control is possible, but additional custom cables are required
from 3rd party manufacturers for full functionality.
Lenses in this range include:
‚ Canon CN-E 18-80mm T4.4 Compact-servo
‚ Canon CN-E 70-200mm T4.4 Compact-servo
