Description
The ARRI Alexa Mini LF is a large-format digital cinema camera built around a large-format version of the ALEXA sensor, combining high resolution with a large pixel size for vivid, nuanced images and smooth bokeh.
Sensor and Formats
The large-format ALEV III sensor supports native 4K recording across three modes — 4448×3096 Open Gate, 3840×2160 16:9, or 4448×1856 2.39:1 anamorphic — in ARRIRAW or ProRes.
Mount Options
The Mini LF is native LPL mount and always ships with an ARRI PL adapter, so the standard option here is LPL & PL Mount together. An EF mount adapter is available separately — select above. LPL/PL pairs with ARRI Signature Primes, Zeiss Supreme Primes and other large-format or Super 35 PL glass; EF opens up the Canon cinema and photo lens ecosystem. The LPL mount’s wider diameter and shorter flange depth make LPL-mount lenses smaller and lighter than earlier large-format optics.
