The specialist - small and lightweight, perfect for 3D or wherever your imagination takes you

The ALEXA M is a flexible solution consisting of a separate camera head and body; it is tailored for action and aerial photography, tight corner shots and 3D productions. Based on cutting edge ARRI technologies, the M model features the same sensor, image processing, build quality, efficient workflows and exceptional image quality that have made ALEXA such a worldwide success.

The head and body of the M are connected with a fiber optic cable, which in a hybrid form can also be used for powering the head. Weighing well under 3 kg, the compact front end offers multiple mounting points and versatile maneuverability. Meanwhile the body provides various options for recording images, sound and metadata, accommodating as many different workflows as the standard ALEXA.

The M also comes equipped with 120 fps high speed functionality as standard (120 fps achievable in 16:9. High Speed mode not supported in 4:3).

ALEXA M unique features
