The Base Plate System for the Canon EOS C80 pairs an ARCA Riser Plate with an ARCA Base Plate, setting the camera at the right optical height for accessories and allowing quick changes between setups. The riser plate works alone with the ARCA Shoulder Plate or ARCA Steadicam Plate; the base plate is needed for tripod or dovetail systems.

The ARCA Riser Plate includes a lens adapter support with an adjustable rail that takes strain from the lens mount to the body and stops accessories such as an RF to PL mount shifting while you adjust lenses. Side-facing 1/4"-20 mounting points let accessories stay on between setups.

On the ARCA Base Plate, the Bridge Plate Dovetail comes off for fitting to a Studio Base Plate or straight to a safety dovetail. It has spacing for LWS accessories such as the Universal Lens Support (15mm LWS), and tie-downs for adjusting the bridge plate's position on accessories like the Safety Dovetail 8", Unified Bridge Plate or Shoulder Rig V3. The system weighs 535.2 g and measures 120 x 117.7 x 70.4 mm.
