The camera lens includes, from an object side, a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a positive refractive power, and a fifth lens having a positive refractive power. The camera lens satisfies specified relational expressions.
Claims5
A camera lens, comprising, from an object side:
- a first lens having a positive refractive power;
- a second lens having a negative refractive power;
- a third lens having a positive refractive power;
- a fourth lens having a positive refractive power;
- and
- a fifth lens having a positive refractive power,
- wherein the camera lens comprises a total of five lenses,
- wherein the camera lens satisfies the following relational expressions (1) to (2):
