ALEXA is not just a camera; it is an advanced technology platform from which ARRI is deriving a comprehensive line of cameras for every production need. In late 2011 the current two models, ALEXA and ALEXA Plus, will be joined by a new and unique camera, the ALEXA Studio. As the top-of-the-line model, ALEXA Studio will have an optical viewfinder and a 4:3 sensor. Soon afterwards a fourth camera will be added to the lineup, the ALEXA M – a flexible and compact solution consisting of separate camera head and body.
