The ARRI EF Mount is an EF lens mount with an LBUS connector and reduced internal reflection properties that ensure the full contrast of the image from the lens reaches the sensor. This EF mount (LBUS) has a wide light baffle that illuminates both Super35 and large-format sensor areas. It allows control of the electronic iris in many EF lenses through the camera menu and ARRI ECS devices. It also allows the use of the electronic image stabilization found in some EF lenses.
Note:
This EF Mount (LBUS) is compatible with ALEXA 35, ALEXA Mini LF, and ALEXA Mini. It does not work with the AMIRA.
