The Alexa Mini LF can use multiple frame lines simultaneously, including a vertical 9:16 crop for social media, which takes advantage of the camera’s tall ARRI sensor. The camera integrates ARRI’s REVEAL Color Science for improved post-production workflows, ensuring high-quality color grading and consistency.
In terms of connectivity, the camera provides a 6G SDI output for 4K monitoring, an EXT port for remote camera control, and built-in genlock for synchronizing multiple cameras. The Mini LF also supports 12V and 24V power outputs for external accessories.
It has interchangeable lens mounts, including the LPL and PL mounts, and comes with an adapter for easy switching between the two. The camera also offers additional lens options with the EF LBUS mount and the Leitz M mount. It supports lens data transmission via LDS, LDS-2, and Cooke/i, ensuring compatibility with a wide range of professional lenses.
Overall, the Alexa Mini LF is a flexible, multi-format camera designed to meet the demands of modern filmmaking, with a wide range of lens options and high-quality imaging capabilities.
