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. ALEXA Classic camera models are the ALEXA, ALEXA Plus, ALEXA Plus 4:3, ALEXA M, ALEXA Studio, ALEXA HD and ALEXA HD Plus. The ALEXA HD and HD Plus are the basis for the ALEXA Fiber Remote and Fiber Remote Plus camera sets. All ALEXA Classic cameras are equipped with an SxS Module located on the left side of the camera with two slots for SxS PRO cards.
Please note that ALEXA Classic cameras can be upgraded with the XR Module and other parts for most of the features of the XT cameras except Open Gate mode.
Second generation ALEXAs are called ALEXA XT cameras (Xtended Technology). They were released in 2013 and, in addition to all the features of the ALEXA Classic cameras, they are equipped with the XR Module (Xtended Recording), internal ND filtration, a 4:3 Super 35 sensor, Open Gate sensor mode, integrated CDL capture and an LDS PL mount. In addition, they have a new viewfinder mounting bracket, include anamorphic de-squeeze and high speed licenses as well as a new, super silent fan. ALEXA XT cameras are the ALEXA XT, ALEXA XT M, ALEXA XT Plus and ALEXA XT Studio. The XR Module is on the left side of the camera. It has one slot for either an XR Capture Drive, the SxS Adapter for use with one SxS PRO card or the CFast 2.0 Adapter for use with one CFast 2.0 card.
