Zoom
On the underside of most B4 handgrips, you’ll find a ‘zoom’ switch that can be set to ’servo’ or
‘manual.’ This controls zoom behavior.
Servo
Set this switch to ‘servo’ or ’s’ to enable servo zoom control. In this mode, the rocker
switch on your handset can be used to zoom your lens in and out, as well as any other
zoom related controls, such as zoom speed and quickzoom. Your lens will also accept
zoom commands from URSA Broadcast and ATEM switchers, so long as it is connected
to the camera via the 12 pin hirose connector. In this mode, you typically can’t adjust
your lens's manual zoom ring.
Manual
Set this switch to ‘manual’ or ‘m’ to disable servo control and adjust zoom using the
zoom ring on your lens barrel. In this mode, your lens will not accept zoom commands
from the handgrip, URSA Broadcast, or ATEM switchers.
TIP
Handgrip zoom rockers are typically linked to zoom speed. Push the
rocker down gently to zoom slowly, push down harder to zoom more rapidly.
