Camera lens
A camera lens includes, arranged sequentially from an object side to an image side: a first lens with positive refractive power; a second lens with negative refractive power; a third lens with positive refractive power; fourth lens with positive refractive power; and a fifth lens with negative refractive power. The camera lens satisfies specific conditions.
