Canon started out as a company with a handful of employees and a burning passion to produce the finest optical equipment available. That company soon became a world-renowned camera maker and is now a global multimedia corporation. Their ongoing development of new and existing technologies has given Canon hi-ranking status as manufacturers of extremely fine broadcast cameras, lenses, and accessories.
