More perspective from Mark Dando @ Codex: https://codexdigital.com/alexa_65

 

 

 

When did ARRI ask Codex to become involved with the ALEXA 65?

It must be over 2 years ago I first had discussions with Franz Kraus about how a digital 65mm camera would make the format much more accessible. Things got serious at Camerimage 2012 when I discussed the idea further with Bill Lovell from ARRI Media who was very excited about this camera system. My last conversation with Bill was about the camera. When he found out I was walking through Soho, he found it very amusing that we were discussing our “dirty little secret” as he called the project – this was typical of Bill.
