Canon Patents EF 600mm f/4 DO IS USM Lens

According to the Egami Blog, Canon has filed the optical formula patent for a EF 600mm f/4 DO IS USM.

This would be an awesome addition to Canon's super telephoto lens lineup. I think professional sports and wildlife photographers will be lining up for this lens. [Sean]
