Unified Baseplate (Sony FS7, Canon C100mkII, C300mkII, C100, C300, C500) is a quick release baseplate that provides lightweight 15mm rod support at the correct lens height. 15mm rods pass through front to back and have two locking thumbscrews per side. The baseplate quick releases in two ways, giving the user the option to take the 15mm lightweight rods or to leave them behind.
