ALEXA LF (Large Format) has the same ALEXA family’s optimal pixel size for best overall image quality in a sensor format slightly larger than full frame. ALEXA LF records native 4.5K and offers three different sensor modes, as well as efficient ProRes and uncompressed, unencrypted ARRIRAW up to 150 fps. This allows filmmakers to explore an immersive large-format aesthetic while retaining the sensor’s natural colorimetry, pleasing skin tones and stunning capability for HDR and WCG workflows. ARRI’s large format camera system comprises the ALEXA LF camera, ARRI Signature Prime lenses, LPL lens mount and PL-to-LPL adapter. These system elements have been designed to take full advantage of the enlarged sensor, while also offering compatibility with existing lenses, accessories and workflows.

ALEXA SXT cameras (Super Xtended Technology) were released from 2016 on. While keeping the sensor and user interface of the original ALEXA design, the capabilities of ALEXA SXT cameras have been greatly extended. Equipped with the powerful electronics and sophisticated image processing of the ALEXA 65, SXT cameras can manage more recording formats and handle more processor-intensive tasks such as calculating looks with 3D LUTs or color space conversions to Rec 2020, all in real time. Building on work done originally for the ALEXA Mini and AMIRA, the new ARRI look management and optional noise reduction help creative filmmakers get their ideas across. And last but not least, the new media bay can accept a wide range of media, as well as the new, high-performance SXR Capture Drives. ALEXA SXT cameras are the ALEXA SXT W, ALEXA SXT EV, ALEXA SXT Plus and ALEXA SXT Studio. The SXR Module is on the left side of the camera. It has one slot for either the XR Adapter for use with an XR Capture Drive, the SXR Adapter for use with an SXR Capture Drive, the SxS Adapter 2 for use with one SxS PRO or SxS PRO+ card or the CFast 2.0 Adapter 2 for use with one CFast 2.0 card.

ALEXA Mini is a versatile additional tool in the ARRI ALEXA camera range, combining a compact and lightweight form factor with the same unparalleled image quality that has made ALEXA a gold standard for the industry. Designed for specialized shots and for working with gimbals and drones, the ALEXA Mini perfectly complements a full ALEXA shooting kit and allows crews to keep everything within a single system. To maintain ARRI's famously rugged build quality in such a small camera body, unique design solutions such as environmentally sealed electronics, a lightweight carbon housing and a solid titanium PL mount have been incorporated. Nimble in use and hardy on set, ALEXA Mini can be operated by wireless remote control, as a normal camera with the ARRI MVF-1 multi viewfinder attached, or with an on-board monitor and controlled via the camera’s user button interface.
