Since the moment it was launched, ALEXA has had a profound impact on the industry, redefining the limits of digital motion picture capture with efficient workflows and incredible image quality. Adoption of the system has been widespread and swift, with the cameras now in use on every possible type of production, from episodic TV shows, documentaries and commercials to feature films of all budgets and prestigious, international drama series.
More than just a camera, the ALEXA platform is the most complete digital camera system ever built, with different camera models for everyday shooting as well as specialty applications and a close integration with ARRI’s wide range of mechanical accessories and electronic, cabled and wireless accessories.
ALEXA’s stellar overall image quality makes ALEXA productions future-proof, no matter what the intended delivery format, with images that look spectacular in HD, 2K, 4K UHD or 4K Cine. Thanks to the camera’s unequalled exposure latitude, ALEXA images are already High Dynamic Range (HDR), so the new HDR display technology will bring out even more of their beauty. And since ALEXA can shoot up to 120 fps in full quality, it can also deliver High Frame Rate (HFR) material for higher temporal resolution. All in all, ALEXA remains the safest capture tool for asset longevity, no matter what future standards come to fruition.

First generation ALEXAs are called ALEXA Classic cameras. They were released between 2010 and 2012. They have exceptional image performance and are simple to operate, reliable in the most extreme environments and versatile enough to cover a wide range of workflows and budgets. They will empower you to tell your story with pictures of breathtaking richness and detail. ALEXA Classic camera models are the ALEXA, ALEXA Plus, ALEXA Plus 4:3, ALEXA M, ALEXA Studio, ALEXA HD and ALEXA HD Plus. The ALEXA HD and HD Plus are the basis for the ALEXA Fiber Remote and Fiber Remote Plus camera sets. All ALEXA Classic cameras are equipped with an SxS Module located on the left side of the camera with two slots for SxS PRO or SxS PRO+ cards.
ALEXA Classic cameras can be upgraded with the XR Module and other parts for most of the features of ALEXA XT cameras except Open Gate sensor mode.
ALEXA – The Original
Where it all began: The classic ALEXA with its 16:9 sensor is compact and affordable, with ultra-fast workflows and image quality akin to 35 mm film.
XR Module Upgrade
An upgrade for ALEXA Classic cameras that replaces the SxS Module with the XR (Xtended Recording) module. The XR module provides in-camera ARRIRAW recording up to 120 fps, compatibility with XR Capture Drives and CFast 2.0 cards, faster ProRes and DNxHD frame rates and longer recording times.
ALEXA Fiber Remote
ALEXA’s superior image and product quality, transformed for the needs of broadcast style multi-camera productions with live editing and live painting.
Second generation ALEXAs are called ALEXA XT cameras (Xtended Technology). They were released in 2013 and, in addition to all the features of the ALEXA Classic cameras, they are equipped with a Super 35 sensor (with Open Gate and 4:3 sensor modes), in-camera ARRIRAW up to 120 fps, ProRes 4444 XQ, ProRes 3.2K, internal ND filter, Lens Data System, integrated CDL capture and ARRIRAW checksum. In addition, they have a new viewfinder mounting bracket, include anamorphic de-squeeze and high speed licenses as well as a new, super silent fan. ALEXA XT cameras are the ALEXA XT, ALEXA XT Plus, ALEXA XT M and ALEXA XT Studio. The XR Module is on the left side of the camera. It has one slot for either an XR Capture Drive, the SxS Adapter for use with one SxS PRO or SxS PRO+ card or the CFast 2.0 Adapter for use with one CFast 2.0 card.
ALEXA XT – ALEXA Reloaded
Super 35 sensor (with Open Gate and 4:3 sensor modes), in-camera ARRIRAW up to 120 fps, ProRes 4444 XQ, ProRes 3.2K, internal ND filter, Lens Data System, integrated CDL capture, ARRIRAW checksum and a new viewfinder bracket – what’s not to love?
ALEXA XT Plus – The Allrounder
The Swiss army knife of cameras: all the features of the ALEXA XT, with built-in wireless remote control of camera and lens motors, an additional HD-SDI and RS output, tilt and roll sensors, electronic horizon and a DNxHD license.
ALEXA XT M – The Specialist
The ALEXA XT M is ideal for helicopter, underwater, car, action, Steadicam and handheld shots, as well as 3D rigs. A thin fiber optic cable connects the compact camera head to the body, allowing extremely flexible configurations.
ALEXA XT Studio – The Flagship
A cinematographer’s dream: all the features of the ALEXA XT Plus, but with a film-style optical viewfinder, rotating mirror shutter and motorized ND filter.
