ARRI introduces a complete large-format system that meets and exceeds modern production requirements, delivering unprecedented creative freedom. Based on a large-format 4K version of the ALEXA sensor, the 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 fullest advantage of the enlarged sensor, while also offering compatibility with existing lenses, accessories and workflows.
Pulling audiences into the image
Much like ALEXA 65, ALEXA LF images are truly immersive, heightening emotion and intensifying character with an intimate, three-dimensional feel that draws the viewer in further.
Large-format aesthetic with ALEXA image quality
Featuring a sensor slightly larger than full frame, ALEXA LF records native 4K with ARRI’s best overall image quality. 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 work flows. Versatile recording formats, including e efficient ProRes and uncompressed, unencrypted ARRIRAW up to 150 fps, encompass all on-set workflow requirements.
Three sensor modes for limitless applications
ALEXA LF has the largest sensor of any full-frame cinema camera on the market. Maintaining the ALEXA family’s optimal pixel size for highest overall image quality results in a 4448 x 3096 picture, which can be recorded in full using the LF Open Gate mode. An LF 16:9 mode maximizes lens options while meeting 4K deliverable standards,
and an LF 2.39:1 mode combines a cinematic widescreen image with high frame rates up to 150 fps for sensuous slow motion. All sensor modes o er true 800 ASA sensitivity as well as reduced noise, providing the perfect canvas for modern, subtle lighting techniques.
ALEXA LF is based on the proven, robust ALEXA camera design, so all existing accessories will work right out of the box. Since all other features and the user interface are the same as in the ALEXA SXT W—including the integrated wireless video transmitter and the user interface—crews will adapt quickly.
Simple ARRI workflows
ALEXA LF offers the same tried-and-true, versatile workflows as other ALEXA cameras. Recording at various resolutions is possible in uncompressed, unencrypted ARRIRAW or fast, efficient ProRes. Existing ARRI Look Files can be used with ALEXA LF, and the entire range of ARRI workflow software tools will support ALEXA large-format images. Lens metadata can be recorded from LDS-1, LDS-2 or /i capable lenses.
