The Arri Alexa is a digital motion picture camera system developed by Arri. The Arri Alexa was introduced in April 2010 and was Arri's first major transition into digital cinematography, after previous efforts including the Arriflex D-20 and D-21.
Alexa cameras are designed to be used in feature films, television shows and commercials. Alexa uses the ALEV series of image sensors manufactured by ON Semiconductor.
Arri Group (/ˈæri/) (stylized as "ARRI") is a German manufacturer of motion picture film equipment. Based in Munich, the company was founded in 1917. It produces professional motion picture cameras, lenses, lighting and post-production equipment. It is cited by Hermann Simon as an example of a "hidden champion". The Arri Alexa camera system was used to shoot several films that won the Academy Award for Best Cinematography, including Hugo (2011), Life of Pi (2012), Gravity (2013), Birdman (2014), The Revenant (2015) and 1917 (2019).

Cinematographers use a lens to focus reflected light from objects into a real image that is transferred to some image sensor or light-sensitive material inside the movie camera. These exposures are created sequentially and preserved for later processing and viewing as a motion picture. Capturing images with an electronic image sensor produces an electrical charge for each pixel in the image, which is electronically processed and stored in a video file for subsequent processing or display. Images captured with photographic emulsion result in a series of invisible latent images on the film stock, which are chemically "developed" into a visible image. The images on the film stock are projected for viewing in the same motion picture.
