Using Box Lenses
Large studio box lenses like Fujinon’s UA series and Canon’s CJ series lenses can also be used
with URSA Broadcast or URSA Mini Pro’s B4 mount. These types of box lenses allow horizontal
and vertical image stabilization on studio style 27x lenses, as well as extreme zoom ranges with
80x, 86x, 90x and even 107x magnification which are incredible for broadcasting sports and
outdoor events.
The large size and high power draw of box lenses means that you will need to setup
your camera correctly on a heavy duty tripod or pedestal, with adequate spacing.
This is possible with URSA Mini Shoulder Kit, a VCT-14 plate and a box lens adapter.
Plug the 12 pin Hirose connector from the lens into URSA Broadcast or URSA Mini Pro’s 12 pin
lens connector. Add additional power to the lens by using an URSA 12 volt power supply, or
if you are using Blackmagic Camera Fiber Converter, you can run additional power from the
12 volt D-tap output on the side of the unit.
Add additional power to your box lens by plugging in a 4 pin XLR cable
Once additional power is connected, you can power up your camera and control the lens with
your URSA Broadcast or URSA Mini Pro.
