Abstract
An optical camera lens including a first lens, a second lens, and a third lens arranged in sequence from the object side to the image side. The first lens has a positive refractive power, and includes a first object side surface and a first image side surface opposite to the first object side surface. The second lens has a negative refractive power, and includes a second object side surface and a second image side surface opposite to the second object side surface, wherein the second image side surface is concave. The third lens has a positive refractive power, and includes a third object side surface and a third image side surface opposite to the third object side surface, wherein both the third object side surface and the third image side surface are convex. The optical camera lens satisfies the following condition: 2<(f+BFL)/OD1<7.
