Camera lens
The present disclosure provides a camera lens including six lenses, having good optical characteristics, having a wide angle and having a bright F number. The camera lens includes, from an object side: a first lens having a negative refractive power; a second lens having a positive refractive power; a third lens having a positive refractive power; a fourth lens having a negative refractive power; a fifth lens having a positive refractive power; and a sixth lens having a negative refractive power. The camera lens satisfies prescribed conditions.
