HOME / / Arri / Alexa Mini LF
 
Alexa Mini LF

The ARRI ALEXA Mini LF camera offers native 4K recording in three sensor modes, with ARRIRAW or ProRes recording in LF Open Gate, LF 16:9, or LF 2.39:1 mode. The ALEXA Mini LF combines large-format resolution with an optimal pixel size for excellent image quality producing vivid, nuanced images with natural skin tones and smooth bokeh. 
 
The ALEXA Mini LF is a hybrid of the ALEXA Mini and the ALEXA LF, as it retains the same LF sensor but has the form factor of the Mini. The Mini LF offers an array of recording format choices in MXF ARRIRAW and MXF ProRes, recording to 1TB Codex capture drives. With a base sensitivity of EI 800, 16-bit processing, and a dynamic range of 14-plus stops, your footage is effectively future-proofed for compatibility with HDR displays. Frame rates up to 90 fps produce smooth slow motion and enable capture for higher-clarity HFR (High Frame Rate) projects.
