Abstract
A photographing lens of a camera comprises a non-circular lens and a light blocking mask. The non-circular lens receives an optical image from an object and forms an image on a photographing medium. The light blocking mask is fixed in front of the non-circular lens, and blocks noise light generated in relation to the non-circular lens.
