Motion picture camera leader, ARRI, this week announced the ALEXA 65, their latest addition to a distinguished line of professional-grade cameras. Available only as a rental through ARRI Rental’s dealer network, the ALEXA 65 is designed to allow filmmakers the ability to recapture the golden age of 65mm widescreen with stunning clarity and image quality for ultimate visual impact.    

While ARRI adding an amazing camera from time to time isn’t new, the sheer magnitude of this ALEXA 65’s capabilities most definitely is. Probably the folks at ARRI Rental describe the amazing sensor in the ALEXA 65 best.

At the heart of the ALEXA 65 is the A3X sensor; the largest high-performance motion picture sensor available on the market today. The sensor has a 54.12 mm x 25.59 mm active imaging area, which is even larger than the film gate of ARRI’s 765 65 mm film camera.[image:blog_post:51891]

The maximum recordable resolution from the A3X sensor is 6560 x 3102 photosites, with a dynamic range of more than 14 stops. The sensor design is based on the same photosite technology as the ALEXA XT, therefore image attributes such as colorimetry and dynamic range will match well with any member of the ALEXA family. This allows productions the freedom to mix the use of 35 mm format ALEXA XT cameras with the larger 65 mm format ALEXA 65, without having to worry about adopting different workflows or any additional color correction of images in postproduction.

Aside from a slightly wider body, the ALEXA 65 is similar in design to the 35mm ALEXA. As far as the workflow goes, the Codex Vault will handle RAW data from the ALEXA 65 as they do for regular ALEXAs.
