Abstract

A lens cap includes a main ring 10 having two tongues 11 extending from a front side thereof and diametrically corresponding to each other. A first cover and a second cover 30,31 are pivotally mounted to selectively close the main ring, wherein the main ring is used as a lens cap when the first cover and the second cover close the main ring and used as a lens hood when the main ring is opened. Two levers 20 are laterally mounted to a rear side of the main ring for selectively positioning the first cover and the second cover when closing the main ring. A connecting ring 60 is mounted to the rear side of the main ring for preventing the two levers from detaching from the main ring, wherein the connecting ring is adapted to be mounted onto a lens of a camera.
