Using Servo Zoom Lenses
Your URSA Broadcast camera natively supports servo driven B4 broadcast lenses.
B4 broadcast lenses offer several features that aren’t typically present in still photography and
cinema lenses. In addition to the ability to hold focus through a large zoom range, these lenses
are distinguished by handgrip controls and servo driven iris and zoom functions. Some lenses
also feature servo driven focus. With the 12 pin hirose connector fitted, iris and zoom can be
controlled from the handgrip, from your camera or even remotely through an ATEM switcher.
Lenses with servo focus can all accept auto focus commands from a camera or switcher.
B4 Lenses with iris and zoom control include:
Fujinon B4 lens models with HA, ZA, XA and UA prefixes in their model name and RM
in their suffix. For example, Fujinon
XA
20sxB
RM
.
Canon B4 lens models with HJ, KJ and CJ prefixes and IRSE or IRSD in their suffix.
For example for example Canon
KJ
20x8.2B
IRSD
.
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. For example, Fujinon
HA

.
Canon B4 lens models with HJ, KJ..ex and CJ prefixes in their name and the letters
IASE or IASD in the suffix. For example, Canon

It’s important to set these functions properly so your URSA Broadcast operates as expected.
Follow these simple steps to configure your B4 lens and start shooting.
