Arri Alex XT Plus camera

For the most effective use of anamorphic lenses, each ALEXA XT model is equipped with an Open Gate sensor of the same size and shape as a Super 35 mm film frame, a feature only found on ALEXA digital cameras. The 4:3 sensor mode is crucial for delivering the unique and cinematic widescreen look that can trace its origins back to the CinemaScope films of the 1950s. It is a look that has long been appreciated by cinematographers, directors and the viewing public. For convenient viewing of anamorphic images an anamorphic de-squeeze license is included with all ALEXA XT cameras.
