ARRI Rental proudly introduces the ALEXA 65 system, available exclusively through its global network of rental facilities. Offering a complete large-format solution for high-end theatrical motion pictures, the system comprises a 65 mm digital cinema camera, custom-designed prime and zoom lenses, and fast, efficient workflow tools. The ALEXA 65 camera is a scaled-up version of an ALEXA XT, able to capture an uncompressed ARRIRAW 65 mm image of staggering intensity and definition.
With a sensor larger than a 5-perf 65 mm film frame, ALEXA 65 harks back to the golden age of 65 mm widescreen filmmaking in the mid-20th century, when this newly introduced format captured the imagination of cinema audiences around the world. 65 mm grew into an inspirational format, providing an epic frame within which the biggest and most visually impactful stories could be told.
In many ways ALEXA 65 represents the evolution of ARRIs 765 65 mm film camera, first introduced in 1989 and used over the last quarter-century by major cinematographers on feature films including Far and Away, Little Buddha, Hamlet, Sunshine, The International, Shutter Island and Gravity. Whether for an entire movie or selected sequences, filmmakers have long valued the opportunity to capture images in the 65 mm format, with its immersive levels of detail and rich cinematic heritage.

In common with ALEXA XT, ALEXA 65 captures in the ARRIRAW format, which delivers uncompressed, uncompromised, unencrypted images. ARRI Rental has worked closely with Codex during the camera development to create a new high-performance workflow unique to the ALEXA 65, which processes full resolution uncompressed ARRIRAW 65 mm images. Depending on your shooting environment and location, the workflow can run on either a purpose-configured ARRI Rental Vault S or the new high performance ARRI Rental Lab 65.
This new, optimized workflow can also generate high quality ProRes 4444 HD dailies masters in real time to provide a very quick dailies solution given the large format nature of the recorded image. These files can then be further transcoded, if required, to other formats.

The ALEXA 65 sensor itself has exactly the same photosite design as that found in ARRI’s successful 35 mm format ALEXA digital cameras, aside from being much larger. The individual photosites on the ALEXA sensor are of an optimal size, carefully balancing the various different parameters involved in maximizing image quality.
With an open gate resolution of 6560 × 3102 photosites, ALEXA 65 offers the same incredible sensitivity, high dynamic range and natural colorimetry as ALEXA, but far greater spatial resolution. This results in images that will look stunningly life-like on the largest cinema screens, with pristine clarity and incredibly fine detail.
