5 Introduction to ALEXA
ALEXA is a 35 format film-style digital camera made by ARRI, the world
leader in professional cinematographic imaging. It combines leading
edge digital technology with film camera features that have been
refined over the more than 90 years of ARRIs history. The result is a
camera that allows classic cinematographers to shoot digitally without
the need for a excessive training when transforming from film.
People who are used to shoot digitally will experience a camera like
they never did before, providing more powerful features than any
camera available today.
Handling
The camera is a true ARRI. It has a high-precision integrated camera
housing with an ergonomic design. It is rugged, reliable and flexible.
Sealed to make it splash-proof. Countless mounting points for
accessories, as ALEXA integrates well with existing ARRI accessories. In
addition, a new range of accessories specifically designed for ALEXA is
available, too.
Operation
ALEXA features a unique user interface, designed to make camera
operation easier than ever, while giving access to more controls than
any camera before.
There are three different control interfaces:
• The Main user interface on the right side gives access to every
camera parameter through a graphical display and a button
panel.
• The Operator user interface on the left side for basic control,
adjustable to the operator's individual needs by supplying
assignable buttons in addition to function buttons.
• The viewfinder user interface for adjusting the most important
image parameters with buttons on the viewfinder and the
interface graphics overlayed to the viewfinder image.
Power management
The camera accepts any input voltage from 11-34 V DC. Different power
sources can be connected to the camera at once. The camera's power
management ensures that the power source with the highest voltage
level is used. Power sources are hot-swappable to minimize the risk of
sudden power loss. Switching power sources without the need to
reboot saves valuable time during a shoot.
