Camera plates required for Steadicam® Ultra 1 with ARRI ALEXA Mini, Mini LF, and ALEXA 35

What the thread found

  • The ARRI ALEXA Mini mounts directly to a standard Steadicam® plate.
  • The ARRI ALEXA Mini LF requires an ARRI SAM-2 adapter; the SAM-2 kit is also useful when working with the original Mini.
  • The ARRI ALEXA 35 can mount with either the ARRI SAM-7 plate or an Apex Cinema Gear A35 plate.
  • Third-party manufacturers offer a flat Steadicam® LF plate; the same vendor also produces an ALEXA 35 variant.
  • The ARRI SAM-7 plate is longer and more rigid than the Apex A35 plate and is favored by operators; the Apex plate serves well as a backup or second rig option.
