The Phantom VEO Adapter Plate Kit effectively turns the Phantom VEO cameras into an Alexa Mini in terms of mounting hole patterns and lens height. These plates allow you to attach the Unified Cage (Alexa Mini), Quick Cage (Alexa Mini + LW), and Fixed Cage (Alexa Mini). ARRI and other third party cages for Alexa Mini are also compatible.
It attaches by two 1/4-20 screws on each plate and provides multiple M4 holes with a variety of spacings for you to choose where you'd like the Alexa Mini cage pieces to fit. This same M4 hole pattern also allows for attachment of ARRI brand handles and accessories.
