ALEXA SXT Goes Wireless
T

he ALEXA SXT platform has been upgraded to
make it an entirely wireless professional motion
picture camera system.
In a move that will increase efficiency on set,
ARRI has integrated a high-quality and low-latency
HD video transmitter and a WiFi radio into the new
ALEXA SXT W model ("W" for Wireless). Based on
the popular ALEXA SXT Plus, the SXT W will replace
the ALEXA SXT Plus and ALEXA SXT Studio models.
As always, there are attractive upgrade options for
existing owners of ALEXA SXT EV and ALEXA SXT Plus
cameras.
Having a video transmitter built into the ALEXA
SXT W makes the camera smaller and lighter than
it would be with an external transmitter, and avoids
the associated cable problems. Camera setup will be
quicker and productions will be able to move faster,
freed of the necessity to route video cables.
Wireless Options
In addition, the integrated WiFi radio opens a
whole range of options, starting with wireless color
management on set and continuing with wireless
camera remote control with the ALEXA Web

Remote. Other exciting WiFi options are currently in
development.
"Our wireless video uses technology from market
leader Amimon, with special hardware and software
modifications to comply with ARRI's stringent
performance and quality requirements," says Marc
Shipman-Mueller, ALEXA Product Manager. "But
that is not all; the wireless video system works
harmoniously with ALEXA SXT's other radio-based
offerings - the WiFi and our own proprietary camera
and lens control system - avoiding time-consuming
interference between the radios on the camera."
The ALEXA SXT W forms part of a new and complete
ARRI Wireless Video System (WVS), along with a
stand-alone video transmitter for use with other
cameras such as the ALEXA Mini, and a standalone video receiver for receiving signals from
either transmitter. An extensive accessory range
includes mounting brackets, antenna extensions, the
handheld Director's Monitor Support (DMS-1), and a
specially adapted Transvideo monitor with a built-in
receiver for the ARRI transmitters.
"We are very proud of our joint effort with ARRI on
their new wireless ALEXA SXT," says Ram Ofir, CEO of

RRI has announced new diopter options and
versatile on-set crew supplies, expanding the
company's PCA range of Pro Camera Accessories.

Diopter Accessories
A new ARRI frame and stage are being introduced
for mounting 138mm close-up diopters, as well as an
adapter that also permits 4.5" diopters to be used
with either.
Diopter Frame 138mm: The diopter frame
allows 138mm diopters of up to +2 to be used in a

lightweight matte box such as the ARRI LMB-25. The
frame has the width of two 4" x 5.65" filter frames
and fits into a two or three-filter stage. A safety
mechanism prevents the diopter from falling out of
the frame during exchange, while two ¼" threads
permit the frame to be attached to an articulating
arm.
Diopter Stage 138mm: The diopter stage can be
used at the back of a 4" x 5.65" clip-on matte box, or
independently with a rear-mounted clamp adapter.
Diopters up to +3 can be fitted, and the position of
split diopters can be adjusted with an integrated
friction wheel. As with the diopter frame, a safety
device and ¼" mounting threads are
included.
