There is a reason why ARRI has now been the leader in pro digital cinematography with their arsenal of Alexa's, Alexa Mini, Amira and who knows what's in the future.
They call this the Alexa but reloaded. And with good reason. An amazing amount of upgrades come with the XT such as open gate and 4:3 sensor modes, in-camera ARRIRAW up to 120fps, Prores 4444 XQ and the list goes on. This camera is stacked and is about as pro as they get.
This version of the Alexa is simply incredible and stacked with amazing tools for big budget-level productions.
