Attaches to the rear body of the Angenieux 24-290 Optimo and supports the Heden M26T motor
. Allows for multiple positions on the lens body as well as an adjustable eccentric for a precise interface between the zoom gear and motor. Includes standard 32-pitch sandwich style gear that won’t slip or bind. Certainly the sexiest way to drive the zoom on your 24-290mm Optimo.
