Arri Alexa
The Arri Alexa is a film-style digital motion picture camera made by Arri first introduced in May 2010. The camera marks Arri's first major transition into digital cinematography after smaller previous efforts such as the Arriflex D-20 and D-21. The Arri Alexa features an advanced electronic viewfinder, modularity, PL mount lenses, and a 35mm-width CMOS sensor shooting up to 2.88k resolution.[1] New features also include recording to the digital intermediate codec ProRes 4444 and ProRes 422 in camera, simplifying the post production workflow.[2]
The camera is designed for use in high budget feature films, television shows, and commercials, and is widely seen as Arri's answer to the growing acceptance of using the Red One, along with lower resolution cameras like the Sony CineAlta (35 mm, 1080p), Panavision Genesis (35 mm, 1080p), Thomson Viper FilmStream (2/3", 1080p) to shoot feature films.
Sensor Information
The Alexa's ALEV III sensor has 3392x2200 pixels that can be used for generating an image. There are more pixels than this, but those extra pixels are used for calibration and other purposes and not for generating an image.[3]
