Introduction to the ALEXA SXT Camera System 11
4 Introduction to the ALEXA SXT Camera
System
ALEXA SXT (Super Xtended Technology) is an extraordinary 35mm format digital
camera system designed for motion pictures and television, consisting of four cameras
and an extensive range of primes, zooms, accessories and recording solutions.
Combining innovative digital technology with a century of ARRI history and experience
has created a camera system that makes it easy to create great looking images.
ALEXA's stellar overall image quality makes ALEXA images future-proof, no matter
what the intended delivery format. Whether in High Dynamic Range (HDR), with
delivery resolutions anywhere from HD to 4K or when being used with spherical or
anamorphic lenses, ALEXA images look spectacular. ALEXA's reliability, simplicity
of operation, as well as unequalled workflow efficiency and versatility ensures lowest
overall production costs.
What's New in ALEXA SXT Cameras?
ALEXA SXT cameras share the same high-performance electronics and image
processing with the ALEXA 65, and the same look management and noise reduction
as can be found in ALEXA Mini and AMIRA. A new media bay allows the use of new
high speed and high capacity SXR Capture Drives, as well as XR Capture Drives, SxS
PRO, SxS PRO+ and CFast 2.0 cards.

All ALEXA cameras provide the best looking digital image with the least amount of
fuss. This is made possible by a unique imaging chain consisting of a high-end optical
low pass filter, a custom made CMOS sensor, as well as custom electronics and
processing software. Carefully crafted by ARRI engineers, these components work
together to produce images with the organic look and feel of film.
The ALEXA has the highest dynamic range of any digital production camera, with
special consideration given to a gentle highlight treatment. Creating a good looking
roll-off in the highlights is probably one of the most difficult tasks for any camera
designer. We have spent enormous resources to ensure ALEXA's outstanding
performance in the critical area between almost overexposed and fully overexposed.
ALEXA footage is (and has been since its introduction in June, 2010) the best starting
point for creating stunning images for the emerging High Dynamic Range (HDR)
display technologies.
By striking a perfect balance between photosite size and number, ALEXA's 3.4K
sensor is able to produce beautiful, natural looking images for HD, 2K, 4K UHD and
4K Cine deliverables.
ALEXA is the only camera on the market with a sensor that is tall enough for
anamorphic lenses to be used just as they were on film cameras. In addition, the
ability to record at up to 120 fps in full image quality means that High Frame Rate
(HFR) shooting can also be accommodated.
ALEXA's high sensitivity and its ability to hold up very well, even when extremely
under or overexposed, work on any real-world set. ALEXA's color processing
was developed by our own color scientists (who have been also working on the
ARRILASER and ARRISCAN, so are intimately familiar with both film and digital color
science), and creates clean and natural colors, especially noticeable in ALEXA's great
looking skin tones. The low noise floor and great color separation helps greatly in color
correction and compositing, aided, when needed, by the mild ARRI Noise Reduction
(ANR).
Our goal is creating the best looking images. When assessing imaging technologies,
we ask if they improve image quality, disregarding the marketing hype.

All productions benefit from using an ALEXA SXT, because of the efficiency and
versatility of the ALEXA workflows. ALEXA SXT cameras can record and play back
ARRIRAW or Apple ProRes in one of 14 recording formats. Whatever the budget,
intended market, resolution requirements, aspect ratio, lens choices or postproduction
intentions, there is an ideal ALEXA SXT recording format to ensure easy operation onset and a seamless image pipeline. ALEXA SXT cameras work with SxS PRO cards,
SxS PRO+ cards, CFast 2.0 cards, XR Capture Drives and SXR Capture Drives.
ARRIRAW is an unencrypted, uncompressed raw image format that contains the full
raw data from the sensor for the absolute best image quality. For greatest flexibility
in post, nothing is "baked" into an ARRIRAW image. Therefore image-processing
steps like debayer, white balance, sensitivity or resampling can be optimized in post,
based on image content and intent. Since we openly publish the ARRIRAW specs,
ARRIRAW is also an excellent future-proof archiving format.
Introduction to the ALEXA SXT Camera System 15
ProRes is the native file format used by Apple's Final Cut Pro software. ProRes
provides a high image quality while using compression to reduce file size and thus
costs. Different ProRes flavors are available with different compression ratios (422,
422 HQ, 4444 and 4444 XQ) for a trade-off between image fidelity and file size/
costs. Productions appreciate the immediacy of ProRes, as it can be viewed on any
Mac without special tools and there is an extensive infrastructure readily available to
process ProRes files. ALEXA is capable of pre-recording with all ProRes recording
formats.
The new ARRI Look Management provides comprehensive look management
from pre-production through post-production, protecting the intended look of the
cinematographer in an easy and transparent manner. The new ARRI Color Tool (ACT)
is used to create the new ARRI Look File (ALF-2), which contains a 3D LUT, CDL
values and the name of the target color space. The ALF-2 look file is always stored in
metadata. A software library enables third parties to incorporate this look management
system into their products, leading to exciting new applications, including live on-set
grading, automated dailies and editing with looks.
Special attention has been paid to provide the most flexible on-set monitoring
experience for the crew. Four independent monitoring outputs (the electronic
viewfinder and three HD-SDI outputs) allow each crewmember to customize the
image they need to see. The HD-SDI outputs support Rec 709 and Rec 2020, as well
as Standard Dynamic Range (SDR) and High Dynamic Range (HDR) monitors. In
addition, the ALEXA SXT W camera can be monitored wirelessly with the integrated
HD video transmitter.
All files recorded with ALEXA SXT contain rich metadata that speeds up postproduction. Metadata is also streamed as part of the HD-SDI outputs for immediate
use.
A number of useful online tools and free Mac programs complete the workflow.
So, disregarding if you want to shoot a low budget TV series or Martin Scorsese's next
big Hollywood feature film, ALEXA SXT cameras can be easily configured for the task
at hand.

ALEXA SXT cameras are part of a long heritage of cameras from ARRI, and we are
quite familiar with the sometimes extreme and nightmarish things our cameras have
to endure in the field. We just have to go into our own service department to see the
carnage. Keeping that in mind, ALEXA SXTs are built to be rugged and reliable with
a sealed electronics compartment, a unique cooling system and the most stable lens/
sensor mount German engineering could devise. A special method of continuously
closing and re-opening container files ensures that very little image data is lost during
a power interruption, and the camera will heal any metadata damage automatically. A
checksum for ARRIRAW ensures safe and fast downloading.
We know what it is like to try to change fps and shutter angle at 4:00 am in the
morning in the rain after a long night's shoot. Professional cameras need to be simple
to operate, and they need to make sure that a good looking image is recorded, no
matter what. For ALEXA we have developed an intuitive user interface that is easy
to learn and quick to operate. The same interface is used on all models of ALEXA,
all with the same on-camera menu, buttons, etc., so there is no learning curve when
using another ALEXA model. Remote control of an ALEXA is possible through the
wireless WCU-4, the cabled and extremely sturdy RCU-4 or through any computer
with the ALEXA Web Remote.
Using internal ND filters allows a rating at the base sensitivity of EI 800 without the
need for external ND filters, even in bright sunlight. ALEXA's Full Spectrum Neutral
Density (FSND) filters offer light attenuation that maintains a neutral color balance at
all densities.
Critically important to camera operators is the viewfinder. Based on our experience
with optical viewfinders, ALEXA's electronic viewfinder provides an exceptionally clear
image with natural skin tones and smooth motion portrayal that is easy on the eye. For
those who prefer optical viewfinders, the ALEXA SXT Studio can be operated with an
optical or electronic viewfinder. The electronic viewfinder includes powerful assistive
displays like surround view, anamorphic de-squeeze, false color exposure check,
smooth mode, peaking and an electronic horizon. In order to check previz footage or
the image from a second camera, ALEXA has a::SPACE SPACE::IN video input, and
when it is critical to perfectly line up a product shot, it is possible to compare a stored
still image with the live camera image.
The hardware of the camera is designed for the best and most ergonomic use on the
set, including a built-in shoulder cut-out, many attachment points on the camera's
precision machined housing and a large variety of accessories. With meticulous
attention to detail we have added many small but helpful design refinements, including
built-in supports for 15 mm lightweight. Additionally, the camera has various extrusions
(eyebrows) above some buttons so the operator can feel the button's position even
from the other side of the camera or when shooting in low light. The same care has
been taken to ensure compatibility with the extensive range of existing accessories.
ALEXAs are well balanced and can be quickly switched from shoulder use to tripod,
crane or Steadicam. They accept a wide range of power input from 10.5 to 34 V DC.
Multiple power sources can be simultaneously connected (with hot-plug capability)
and a smart circuit will automatically switch to the one with the highest voltage.
All ALEXA SXTs are backed by ARRI's global service network, providing a friendly
ARRI service technician accessible 24/5.

•
•
We are open to equipment and standards from other manufacturers, as can be seen
in ALEXA's compatibility with Super 35 PL mount lenses, SxS PRO, SxS PRO+ and
CFast 2.0 cards, Apple ProRes, HD-SDI, Gold or V-mount on-board batteries, the
cmotion lens control system and both 12 and 24V accessories. We want to make sure
that you can put together the right ALEXA package with the accessories you want.
To ensure a smooth workflow, we share our know-how with third parties through
the ARRI Partner Program. The ARRI Look Management library allows third parties
access to all look management functions found in the ARRI Color Tool, including
the ability to change looks live in-camera. The ARRIRAW Software Development
Kit (SDK) allows them to integrate the ARRI debayering algorithm and various other
image processing steps into their own products. The ARRI Metadata Bridge (AMB)
tackles the tricky problem of getting metadata from the ARRIRAW or ProRes recording
files into the file formats (DPX and OpenEXR) of those who can actually benefit from
the metadata. We have published our color science in various white papers and the
ARRIRAW debayering method in two SMPTE Recommended Disclosure Documents
(RDD 30:2014 and RDD 31:2014).
In addition, ALEXAs can be upgraded, as we have shown with numerous hardware
upgrades in the past. The Software Upgrade Packets (SUPs) are continuously
improving ALEXA cameras with new and exciting features. All this, combined with
our long product cycles, creates a sustainable business model for all owners of ARRI
cameras.

•
whenever there is no lens attached.
Unplug all cables when transporting the ALEXA in a camera case.
•
Do not store the camera in places where it may be subject to temperature
•
extremes, direct sunlight, high humidity, severe vibration, or strong magnetic fields.
7.2 Condensation
When moving the camera from a cool to a warm location or when the camera is
used in a damp environment, condensation may form inside the lens port, on the
sensor cover glass, between the sensor and the sensor cover glass, and on internal or
external electrical connections.
Operating the camera while condensation is present may result in personal injury or
damage to the equipment.
Condensation on the optical components may have a visible effect on the output
images. To reduce the risk of condensation:
Find a warmer storage location.
•
Attach the ARRI air-drying cartridge (silica bottle) to the PL-Mount of the camera
•
during storage
Note: Do NOT leave the air-drying cartridge attached to the PL-Mount during
•
transportation of the camera!
If the camera needs to be stored in a place that is considerably cooler than the
•
location where it will be used, consider keeping the camera powered from a mains
unit in addition to using the air-drying cartridge.
In ambient temperatures above 30°C/86°F and/or humidity above 60%, always
•
attach the air-drying cartridge to the PL-Mount of the camera when not in use. This
not only applies to storage, but also to shooting breaks and situations when the
camera remains without an attached lens for an extended time.
MAKE SURE THE SILICA BOTTLE IS SECURELY FASTENED. UNDER NO
•
CIRCUMSTANCES SPILL SILICA INTO THE LENS PORT!
24 Power Supply
8 Power Supply
Use only ARRI-recommended power supply solutions.
•
Manipulation of power supplies could result in serious injury or death, or damage
•
to the ALEXA.
The ALEXA accepts an input voltage range from 10.5 to 34 V DC. Do not supply
power outside the specified voltage range. The camera can be powered through the
BAT connector or battery adapters accepting V-Lock or Gold Mount batteries.
The power supply should deliver an output of more than 90 W to power the camera
sufficiently. The power draw of the camera in basic configuration is about 85 W.
A 12 to 15 V battery should have at least 6 A maximum output current.
NOTICE
When powering accessories through the camera, the total power draw of the
•
camera is increased by the amount of power drawn by the accessories.
Always keep the BAT connector or attached battery accessible so that they can
•
be unplugged quickly in case of emergency.
8.1 Power Management
When using the BAT connector and one or more onboard battery adapters
simultaneously, the camera’s power management system ensures that the power
source with the highest voltage level is used. When the voltage level of one power
source drops below the level of the other, or a power source is disconnected from the
camera, the power management system automatically switches to the other power
source, avoiding shutdown of the camera.
For example, a 12 V onboard battery can be used as backup for the main 24 V battery.
Using a 12 V onboard battery in addition to the main 24 V battery also allows for quick
switchover to handheld mode—the power cable can simply be disconnected from the
BAT connector.
When using two onboard battery adapters (with batteries in parallel—one on top and
one on the back), the camera will treat them as a single source. When used this way,
the load is spread across two batteries, creating a strong power source.
8.2 BAT Connector
The BAT connector is the primary power input on the ALEXA. It is a Fischer 2-pin
socket located at the back of the camera on the camera-right side.
The socket accepts power cables KC-20S and KC-29S. The cables can either be
connected to the mains unit NG 12/26R or to 24 V cine-style batteries with three-pin
XLR outputs. Do not use cables longer than 4m.
Power Supply 25
Fig. 1: BAT connector
8.3 Mains Unit NG 12/26 R
Use of the mains unit is recommended for shooting in the studio and when using
electronic accessories with high power consumption.
To power the ALEXA using the Mains Unit NG 12/26 R:
1. Set the correct mains voltage on the mains unit using the fuse on the back of the
unit. For example, set it to 220 V if the AC mains power source is 220 V.
2. Connect the mains unit to AC mains power.
3. Ensure that the camera power is turned off.
4. Set the voltage switch on the mains unit to 26 V.
5. Connect the battery cable KC-20S or KC-29S (spiral cable) to the power supply
socket on the camera and the 26 V socket on the mains unit.
The NG 12/24 R was the original design that provided 12 & 24 volts output – it was
superseded by the NG 12/26 R, which outputs 12 & 26 volts. The NG 12/24 R can
easily be upgraded to NG 12/26 R specification at an ARRI service center.
8.4 Cine-Style Batteries
Any 24 V cine-style battery with a three-pin XLR output can be used to power the
camera through a KC-20S or a KC-29S battery cable.
To connect the battery to the camera:
1. Ensure that the main switch on the camera is off.
2. Connect the battery cable KC-20S or KC-29S (spiral cable) to the power supply
socket on the camera and the 28V output on the battery.
NOTICE
NOTICE
When the battery voltage drops below the warning level, the BAT1 level in the
camera display will start flashing. A white i will appear, signaling more information
is available on the INFO screen. For more information on setting the low battery
warning level, see Menu>System>Power (on page 110).
