Quick Base (Alexa Mini) attaches to the ARRI Alexa Mini by four M4 screws and features a quick release based on an ARRI standard dovetail shape which lets you separate your camera from the rod system. You can also clamp directly to our Quick Dovetail (Standard), Safety Dovetails, and 2060 Dovetails. To quick release out of dovetail/baseplate, turn thumbscrew, depress pin, move camera toward rear, and remove.
