Abstract
The present disclosure provides a camera lens, constituted by eight lenses, and featuring excellent optical characteristics, an ultra-thin appearance, a wide angle and a bright Fno. The camera lens is configured with, sequentially from an object side: a 1st lens having a positive refractive power, a 2nd lens having a negative refractive power, a 3rd lens having a negative refractive power, a 4th lens having a positive refractive power, a 5th lens having a negative refractive power, a 6th lens having a positive refractive power, a 7th lens having a positive refractive power and an 8th lens having a negative refractive power, and satisfies specified conditional formulas.
