     At the inception of the ALEXA project we looked carefully at what is needed to create digital image and audio in the
     most efficient manner, including what it takes to get that content quickly into post and distribution. During our discussions
     with industry experts, it became obvious that a modern digital camera system requires much more than just a new camera
     with a great sensor - lenses, recording media, recording codecs, electronic accessories, mechanical accessories, batteries
     and post production have to mesh perfectly for a smooth journey of content from set to post. The system has to be complete
     and all its parts tightly integrated. The challenge was tremendous in scope, more vast and complex than the creation of
     the ARRICAM system.
