ARRI ALEXA 65 – THE BIG 6K SHOOTER

And you thought 4K was big? Arri has just announced a 6K 65mm professional cinema camera – the Alexa 65.

There had been rumours for some time that Arri would release a 65mm camera, but it seemed nothing more, until this past weekend’s Cinec event in Munich, where the company finally unveiled the large format Alexa 65.

The new cinema camera’s sensor is 3 times the size of the original Alexa or Super 35. And is similar in size to those 65- 70mm film cameras used in Lawrence of Arabia, Ben Hur, Cleopatra and 2001: A Space Odyssey.

Albeit, the Alexa 65 is a lot lighter than the cameras used in those movies which weighed around 70 lbs/32 kgs, the Alexa 65 sits at 23.2 lbs/10.5 kgs. And unlike those old cameras the Alexa 65 shoots in digital rather than film stock (well, duh).

The sensor has a 54.12 x 25.59-mm active imaging area (diagonal: 59.8-mm), which is even larger than the film gate of ARRI’s old 65 mm film camera (the 765).

The new cam also has 14-stops of Dynamic Range and uses the same photosite technology as the ALEXA XT, so its image attributes such as colorimetry and dynamic range will match all of the other cameras of the Alexa family. The 65 also sits a little fatter than the XT, at 8.2″ wide

Full resolution from the A3X sensor at open gate, is 6560 x 3102, and at 2.11:1 it will chew up 2.6 terabytes an hour shooting in ARRIRAW using the Codex XR media drives, (similar again to the Alexa XT ). There are two crop modes which cost a little less storage to shoot on (but not much), at 1.78  it’ll chew through 1.9 TB per hr and 1.5:1 eating slightly less at 1.6 TB per hr.

Which is why Codex has unveiled two new Vaults for 65, the Vault S and Vault XL, so filmmaker’s will have enough storage on-set (photos and specs for the Vaults are at the end of this article). Keep in mind if you plan on hiring the Alexa 65, that you’ll need to hire one or two Vaults also.

Hasselblad 65 lenses

Along with the new 65mm camera is a new range of lenses from Hasselblad, including a 50-110 mm Zoom 65, along with 8 primes ranging from 24mm to 300mm.

On to the specs.
