The Redrock Micro Adjustable Base Plate for M3 is an adjustable support that aligns your camera vertically with the M3 Cinema Adapter, which enables the use of 35mm lenses with a videocamera. (Both the Adjustable Base Plate and the M3 Cinema Adapter accept standard 15mm rods for sturdy horizontal alignment.) Thumbscrews enable a tool-less setup.
Previous generations of Redrock Micro base plates required the addition of shims to mount the camera to the proper vertical level to align with the Cinema Lens Adapter. This version offers vertical adjustment within the unit to obviate the need for shims.
This camera support ships with 3/8" and 1/4"-20 camera screws.
