Abstract
A camera lens including a first lens, a prism, and a plurality of lenses. The first lens has positive focal power, and an object-side surface of the first lens is a convex surface. An object-side surface of the prism is in contact with an image-side surface of the first lens. The prism refracts, from a first optical axis to a second optical axis intersecting the first optical axis, light received from the first lens. The plurality of lenses include at least three lenses, and the plurality of lenses are sequentially disposed along the second optical axis.
