The Arri Alexa Mini LF offers you the premium, large format look in a package very similar
in size to the popular, super 35 sensor based Arri Alexa Mini.
The colour science from the Mini LF is the same industry standard look as from Alexa LF, Alexa Mini and
Amira cameras - so you know you are getting the best image available today.
The Mini LF includes both an LPL mount and a PL adapter, allowing the use of a range of lenses (a new Canon EF mount
will be available soon).
Choose from a range of recording formats to suit your project requirements and the lenses being used - from LF Open
Gate through to
LF 16:9 or 2.39:1 modes. Talk to us about lens compatibility if you have any questions.
The Mini LF also improves upon the S35 Alexa Mini in some key areas. The EVF cable connector
is now a single pin and cannot be inserted incorrectly. There's a dedicated genlock/sync BNC
jack, rather than this function consuming the second SDI output. The camera body has 12V and
24V auxiliary power connectors for powering accessories directly from the camera body (rather than
via the power distribution box).
