ARRI is announcing the new ALEXA 265 camera. This new generation 65 mm camera is one-third the size and weight of its predecessor, the ALEXA 65. Not only small and lightweight, the ALEXA 265 also features a revised 65 mm sensor that delivers higher image quality through 15 stops of dynamic range and enhanced low-light performance.
