The best just got better

ARRI’s new ALEXA SXT (Super Extended Technology) cameras and SXR (Super Extended Recording) Module upgrade represent the next exciting step in the continuing evolution of the ALEXA family. Retaining the rock-solid foundation on which ALEXA is built, ALEXA SXT and SXR cameras additionally offer ProRes 4K recording, improved image quality, powerful color management, three fully independent HD-SDI outputs and support for the new high-speed, high capacity SXR Capture Drives.

The first ALEXA SXT cameras are planned for release around mid-2015; the full range will comprise ALEXA SXT EV, SXT Plus and SXT Studio models, replacing current ALEXA XT cameras. Due to the launch of ALEXA Mini, there will not be an ALEXA SXT M. The ALEXA Classic EV model will remain in the line-up. ALEXA XT cameras (except ALEXA XT M) shipped between 1st Jan. 2015 and the first shipment of SXT cameras will be eligible for a full SXT upgrade, free of charge.

Ever since its launch, the ALEXA system’s fundamental advantage has been its unique combination of the highest overall image quality with the most efficient workflows on set and in post. Based on extensive market feedback, the ALEXA SXT line of cameras further improves upon those qualities, raising the widely-accepted gold standard set by ALEXA still higher.
