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.
Super 35mm PL lenses with full servo control of focus, iris and zoom include:

Focus and zoom controls can also be used to drive focus and zoom from the pan handles in a
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 4.6K 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 4.6K. 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
NOTE Analog B4 lenses with servos are also supported although the camera will only
power the zoom servo and support electronic iris control. Many of them are standard
definition and may not have the standard 12 pin broadcast connector. If you are going
to use an analog B4 lens, it’s important to make sure it is compatible with your camera
first as some have limited feature sets. It is also worth testing them for their image circle
coverage as some of them may fall off drastically for resolution and light towards the
edge of the frame.
