Arri Alexa LF Pro Set with Four 2TB SXR Drives

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 workflows. Versatile recording formats, including efficient ProRes and uncompressed, unencrypted ARRIRAW up to 150 fps, encompass all on-set workflow requirements.
