The 6K equipped Alexa 65 is a “…complete large-format solution for high-end theatrical motion pictures…”, and is an enhanced version of ARRI’s Alexa XT camera. Its A3X CMOS sensor is the exact same as the one found in ARRI’s 35mm cameras, only obviously larger with its resolution of 6560 x 3102. The Alexa 65 comes with an XPL lens mount with the with the ARRI Lens Data System, letting you use the lenses wireslessly via remote control. Along those lines, ARRI has also released a series of 65mm one zoom and eight prime lenses for the Alexa 65, with the prime lenses ranging from 24mm to 300mm. Finally, it shoots in uncompressed ArriRaw (no option for ProRes) with a dynamic range of over 14 stops in up to 27fps, though an upgrade has been planned for the start of 2015 that will allow shooting up to 60fps.
While we’d usually list the price at this point in the story, however ARRI will not be selling the Alexa 65, only renting it through its rental chain, meaning prices could vary. Availability also seems up in the air right now, though ARRI will be holding a Los Angeles launch for the camera some time this October.
