ALEXA CLASICA & ALEXA PLUS CLASICA
First generation ALEXAs are called ALEXA Classic cameras. They were released between 2010 and 2012. They have exceptional image performance and are simple to operate, reliable in the most extreme environments and versatile enough to cover a wide range of workflows and budgets. They will empower you to tell your story with pictures of breathtaking richness and detail.

BNC connectors designed for fast exchange without camera disassembly have been used for ALEXA since approximately mid 2012. These connectors require a special tool.
SD Card: For importing and storing ARRI Look Files, camera set up files, frame line files, feature license keys and user pixel masks. Stores captured stills from the REC OUT image path in ARRIRAW (.ari, 12 bit), TIFF (.tif, 16 bit), DPX (.dpx, 10 bit) or JPEG (.jpg, 8 bit) format (1). Stores log files. Also used for installing Software Update Packets (SUPs).
(1) When REC OUT is set to 'ARRIRAW', frame grabs are only possible in the .ari format. Frame grabs are not possible during High Speed, 16:9 2K or when the option 'REC OUT = MON OUT Clone' is chosen.
