ABSTRACT:
A lens hood with lens covers that need not be attached to and detached from a lens unit and are easily openable and closable relative to each other. The lens hood includes a hood body attached to the front of a lens to prevent unnecessary light from being incident upon the lens, a pair of lens covers installed inside the hood body to be pivotable about an axis perpendicular to the optical axis of the lens and movable between a closed position where they will cover the lens and an opened position where they will be outside the field of view of the lens, and a cover operating mechanism that operates in conjunction with the sliding of an operator installed slidably to the hood body to pivot the lens covers in opposite directions, respectively, and to pivot the pair of lens covers between the opened and closed positions.
