Description
The Arri Alexa XT (Extended Technology) is the latest evolution from Arri of an already very successful digital cinema camera the Arri Alexa Plus 16:9.
Differently from the Alexa Plus EV and Plus, the Alexa XT features a four third sensor (4:3) meaning that the usable surface of its sensor it is slightly bigger than the one of the Alexa 16:9 and it allows to shoot with x 2.0 anamorphic lenses such as our Cooke Anamorphic/i primes and the Angenieux Optimo 56-152mm 2S T4.
In order to provide the best experience while shooting in Anamorphic format we provide the SmallHD DP7 pro on board monitor that has the un-squeezing features that allows the proper monitoring out on the camera.
The Alexa XT differently from other Alexa models has internal IRND filtration and it can record Arri Raw internally without the need of external recorders.
The Arri Alexa XT is the only digital camera on the market at the moment that shoots in anamorphic format with 2.40 aspect ratio without any crop of the frame.
We recommend a studio set up with 19mm studio rods and matte box if your production is planning to use Cooke Anamorphic lenses and we will also provide in the package a universal lens support to prevent any stress on the positive lock mount.
Finally, if you have the need to shoot in 16:9, but you still want the built in Codex recorder feature you can have the 16:9 (typical of the S35mm) format available also on the Alexa XT.
