The Canon Cinema EOS C80 just arrived, and wouldn’t you know it — Wooden Camera has an Elite Accessory System for it:

Top Plate, a new ARCA Riser Plate, NATO Side Rail, Canon ¼”-20 Ridge Plate, Gold and V-Mount Battery Slide power options, a Core Accessory System letting you use Canon’s Carry Handle, and lots more.

Lots more information here, at Wooden Camera.
