Product Overview



The ALEXA LF is more of an evolution than a revolution. ARRI has taken everything people love about the ALEXA and put it into a camera that solves their problem of not being able to produce a 4k image that isn’t upscaled. The ALEXA LF records native 4K with ARRI’s renowned image quality. The ALEXA sensor everyone loves retains all of the same characteristics while delivering an immersive, larger format aesthetic for filmmakers. ALEXA LF includes the same exposure latitude of 14+ stops as is the case on all previous ALEXA branded cameras. ARRI claims it features low noise while also maintaining pleasing skin tones for both HDR and WCG Workflows. The ALEXA LF also comes standard with a PL-to-LPL Adapter so you can use existing compatible lenses on the new Large Format camera. Like its ALEXA SXT W predecessor, the ALEXA LF camera reduces the number of cables required as a wireless video transmission and remote lens & camera control are built into the camera body.
