The FAQ does a nice job of outlining the differences between the ALEXA XT and ALEXA Classic, as well as covering questions about the XR Module, 4:3 Sensor, and Arri's Lens Data System. For more information on topics such as image processing, workflow, and power, make sure to visit the general ALEXA FAQ. Please note: the ALEXA XT FAQ doesn't repeat any information found in the manual and it applies to ALEXA XT, ALEXA XT M, ALEXA XT Plus and ALEXA XT Studio cameras with Software Update Packet 8.0 (ALEXA XT/XR) or above.
Got a question the ALEXA FAQs don't answer? Let us know in the comments and make sure to check out our Arri workshops coming up on both coasts!
