The Arri ALEXA 65 – 6K and a Giant 65mm Sensor

by Sebastian WöberSeptember 21^st, 2014

Everybody was wondering when Arri would jump into the 4K camera race. Today we were surprised with the announcement of their new 6K camera, the ALEXA 65 that uses a giant 65mm sensor.

The camera’s sensor is a new sensor developed by Arri that is slightly larger than a 65mm 5-perf film frame. Some sites claim that the sensor is comprised of three Alexa sensors that are arranged vertically and seamlessly stitched together.

To cover the large sensor Arri is introducing a new line of lenses based on Hasselblad medium format stills lenses.
This is all very intriguing news. We will let you know when we see the first footage from the camera and get a chance to test and review.
