Introduction to ALEXA How to Read This Manual 11
ALEV III sensor
The ALEV III sensor has a horizontal pixel count of 3.5K resulting in true
2K resolution. It covers the full Super-35 format and it provides a
latitude of more than 13.5 stops at a base sensitivity of 800 ASA. The
result is a superior image quality.
The sensor temperature is kept stable by a Peltier element to ensure
optimum image quality under all operating conditions.
AIT - ARRI Imaging Technology
The ARRI imaging technology ensures the most organic, film-like image
quality of any digital camera with natural color rendition and pleasing
skin tones.
Thermal concept
The camera electronics are fully sealed to protect them from dirt and
moisture. Camera heat is transported via heat pipes to a radiator which
is cooled by the fan. The fan itself is very silent, so the camera noise
floor is below 20 dB (A) - this is the same noise level as with ARRI sync-
sound film cameras. If the fan noise level starts to increase, the fan can
be swapped in a matter of minutes by a trained technician.
EVF-1 electronic viewfinder
ARRI is redefining electronic viewfinders with LED lighting, high
resolution and a viewing experience that comes as close to an optical
viewfinder as possible.
