The ALEXA 65's sensor is around 3x bigger than that of a Super35. ARRI Rental shares plenty of information about the camera. Here's what they have to say about the sensor itself.

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.

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.


Here is some basic information about The ALEXA 65 pulled from the Cinec Munich issue of Jon Fauer's Film and Digital Times.

The new ALEXA 65 has a similar design and ergonomics as the 35mm ALEXA, except that the body is a little wider, adjusted to fit the massive sensor. The ALEXA 65 was designed not just as a standalone camera, but as an entire camera system, complete with lenses and workflow solutions. ARRI has rehoused Hasselblad lenses -- high-performance 65mm primes and zooms, which include a 50-110 mm Zoom 65, as well as 8 primes that range from 24mm to 300mm. As far as the workflow goes, the Codex Vault will "handle RAW data from regular ALEXAs as well as from the ALEXA 65."
If you're wondering if ARRI has any plans to include more lenses or mounts for the ALEXA 65, the answer is -- maybe. Kraus says that it all depends on how well the camera system is received by the industry.

No word yet on prices or availability, but we'll certainly keep you posted.
