ALEXA Classic Family Features

Best Overall Image Quality A great looking image consists of many
parts: the absence of artifacts, high dynamic range, sharp and natural rendering,
high sensitivity, low noise and natural color reproduction. All ALEXA cameras provide
the best overall image quality with the least amount of fuss. To render images with
a film-like, organic look, all components of the ALEXA imaging chain are proprietary
high performance custom designs: the optical low pass filter, the CMOS sensor, the
electronics hardware imaging engine and the image processing software.
The ALEXA sensor provides high dynamic range images through an unequalled exposure
latitude of more than 14 stops (as measured with the ARRI Dynamic Range Test Chart)
with special consideration given to highlight treatment. Creating a good looking
roll-off in the highlights is probably one of the most difficult tasks for any sensor
designer and we have spent enormous resources at insuring exceptional highlight
handling. ALEXA’s wide exposure latitude translates into a ‘thick’ digital negative;
there is more detail information in the highlights and in the dark areas than any
of the current display technologies can disclose. This means tremendous flexibility
when color grading and makes ALEXA images future-proof for high dynamic range (HDR)
display technologies.

Because of ALEXA’s great overall image quality, its images can be easily up
or down-sampled for spectacular HD, 2K, 4K UHD or 4K Cine deliverables. ALEXA’s
high sensitivity and its ability to retain definition even when extremely under
or overexposed make it very easy to work with. ALEXA’s unique color processing was
developed by the same ARRI color scientists that have been working on the ARRILASER
and ARRISCAN; thus they are intimately familiar with both film and digital color
science. ALEXA renders natural colors, great looking skin tones and shows great
color separation while also showing a fantastic ability to resolve mixed color temperature
sources. Efficient and Versatile Workflows ALEXA represents the
most efficient and versatile method to capture and then transport images, audio
and metadata through the production process. This is achieved with a multitude of
in-camera recording options, support for the native codecs of the most popular non-linear
editors, complete rich metadata, integrated color management and a pre-recording
option. So, disregarding if you want to shoot a low budget TV series or Martin Scorsese’s
next big Hollywood feature, you can configure an ALEXA for the task at hand. This
is also great for rentals, who can use the same product for many different customer

alexa-classic-display-2013Simple and Safe Operation
know what it is like to try to change frame rate and shutter angle 12.11.14 in the
morning in the rain after a long night shoot. We know that a camera needs to be
very simple to operate, and everything about its design must ensure that you get
a good image, no matter what. The ALEXA user interface has been specifically developed
to be easy to learn and quick to operate. The same interface is used on all ALEXAs,
with the same menu, buttons, etc., so there is no learning curve when using another
model ALEXA. The hardware of the camera is designed for the best and most ergonomic
use on the set, including the built-in shoulder cut-out, large number of accessories
like the Low Mode Support LMS-3, the Remote Control Unit RCU-4 or the Wireless Compact
Unit WCU-4, down to little details like differently shaped 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. ALEXA cameras are part of
a long heritage of cameras from ARRI, and we are very familiar with the sometimes
horrid conditions our cameras have to endure in the field. So ALEXAs are built rugged
and reliable with a sealed electronics compartment, a unique cooling system and
the most stable lens/sensor mount that German engineering could devise. The camera’s
electronics are housed in a sealed compartment in the center of the body. The heat
generated by the sensor and the electronics is transported via heat pipes to a radiator
located in a ventilation shaft at the back of the camera. A single, slow running
silent fan cools the radiator. If need be, the fan can be easily exchanged. This
system ensures effective, active cooling of the sensor and processing boards even
in the hottest climates. At the same time it protects the electronics, thereby rendering
the camera splash and dust proof.
To further improve the legendary stability of the ARRI lens mount, ALEXA is equipped
with a novel lens and sensor mount design. The stainless steel lens mount is attached
to a stainless steel distance barrel, which itself is attached to the sensor mount,
which also holds the sensor board. The whole unit is then attached to the camera
body. By creating a fixed link between lens and sensor (all the orange parts in
the second drawing), a super stable flange focal depth is ensured – even if strong
mechanical influences are applied to the lens mount, such as when a heavy zoom lens
is not properly supported. Using stainless steel ensures minimum material expansion
or contraction during temperature changes.
Open, future-proof architecture The ALEXA system is based on an open architecture,
with many industry-standard interfaces and compatibility with third party products.
This provides more choice to the filmmaker and ensures that best-of-class components
can be used. To protect customers’ investment in ALEXA, a plethora of affordable
hardware and software upgrades have been promised and delivered, continually expanding
the feature set. Four major components are specifically designed to allow an easy
upgrade and to add new features in order to extend its useful life.

  • First, taking into account the rapid rate of change in storage technologies, the
    in-camera recording module on the left side of the camera is removable, featuring
    an SxS Module for ALEXA Classic cameras (which can be upgraded to an XR Module)
    or an XR Module for ALEXA XT cameras.
  • Second, the camera control electronics on the right side can be replaced with an
    upgrade such as the Plus panel, for wireless camera and lens remote control.
  • Third, the Exchangeable Lens Mount (ELM) allows the use of PL, PL LDS or Panavision
    lenses, further extending creative options.
  • And finally, ALEXA’s processors are based on FPGAs (Field Programmable Gate Arrays),
    a technology that permits the camera’s feature set to be completely re-programmed.
    Thus ALEXAs can be quickly and easily upgraded with our free-of-charge Software
    Upgrade Packets (SUPs) and licenses available for purchase. Past SUPs have added
    exciting features like ProRes 2K, ProRes 4:3, pre-recording, self-healing metadata,
    compatibility with new gear (like the WCU-4, the Ultra Wide Zoom UWZ 9.5 – 18 or
    SxS PRO+ cards) and advances in image quality like greatly improved debayering algorithms.
    Licenses are available to upgrade ALEXAs with high speed, anamorphic de-squeeze
    or the Avid DNxHD codecs.

This great compatibility coupled with ALEXA’s hardware and software modularity allowed
us to keep ALEXA cameras relevant, which translates into a long and reliable product

evf-1_backALEXA Electronic Viewfinder EVF-1
This viewfinder
was specifically designed to meet the needs of professional camera operators by
offering an extremely low latency image display, high image quality, accurate color
reproduction and a number of features inherited from our optical viewfinders, including
a peripheral viewing area we call ‘Surround View’. It is critical to the camera
operator that the action in the viewfinder can be seen at almost at the same time
as the action in front of the camera. The extremely fast image display of the EVF-1
has been made possible through the creation of a proprietary high speed connection
between the viewfinder and the camera, as well as a shared image processing architecture
that maximizes the processing power of both camera and viewfinder. The ALEXA EVF-1
is unique and uniquely suited for work on the set with its image delay of under
one frame. A stable, accurate and high quality image is important for the camera
operator. The EVF-1 image exhibits high resolution, high contrast, low distortion
and an evenly illuminated viewing area. All this has been made possible through
a state-of-the-art F-LCOS (Ferroelectric Liquid Crystal On Silicon) micro display
with 1280 x 768 pixel resolution, a high screen refresh rate and an ARRI optical
design that employs the highest quality coated glass elements. Reliable contrast
and color reproduction at all temperatures are assured through careful thermal stabilization
of both the F-LCOS display and the ARRI custom LED light engine.
The EVF-1 has not only been developed to provide the best possible image, but is
also specifically designed to fit the ergonomic needs of the operator. Even when
using a matte box on a short prime lens, the compact dimensions of the finder guarantee
that the eyepiece can be adjusted to a comfortable position for shoulder operation.
The small, self-contained unit is easily mounted in different positions: on the
left side for handheld, on the right side when the set is tight or further back
through a telescoping extension for use with a geared head. Straightforward operation
is assured through a plethora of assistive displays in the viewfinder (and on the
MON OUT as well), including: preset and custom frame lines, user rectangles, surround
view, camera status, false color exposure check, peaking focus check, compare stored
image with live image, RETURN IN video and an optional anamorphic de-squeeze (license
key required on some ALEXA Classic cameras). A number of ergonomically placed buttons
allow convenient access to frequently used functions such as zoom and false color
exposure check. The viewfinder’s settings, as well as the basic camera settings,
can be changed by the operator directly on the EVF-1. Showing their heritage, ALEXA
and the EVF-1 have been designed to provide some features that previously have only
been available through optical viewfinders. Most important for the operator is the
fact that the camera’s sensor is slightly oversized to provide an extra area around
the primary image in the viewfinder (Surround View). This allows lighting stands,
microphones, etc. to be spotted before ruining the shot. Additionally, the size
of the image in the EVF-1 has been chosen to equal that of the image in the optical
viewfinders of ARRI’s film cameras.

Output Options

ALEXA represents the most efficient and versatile method to capture and then transport images, audio and metadata through the production process. This is achieved with a multitude of output options, support for the native codecs of the most popular non-linear editors, complete metadata and integrated color management. ALEXAs can easily integrate into any digital workflow, be that a high-end Hollywood feature film that shoots ARRIRAW, a TV series that shoots ProRes 4444 Log C or a Telenovella that needs to optimize throughput by shooting ProRes 422 Rec 709.
