Abstract: A zoom lens includes, in order from an object side to an image side, a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, a third lens unit having a positive refractive power, a fourth lens unit having a positive refractive power, a fifth lens unit having a negative refractive power, a sixth lens unit having a positive refractive power, and a seventh lens unit having a negative refractive power. During zooming, a distance between adjacent lens units changes, the first lens unit, the second lens unit, and a plurality of lens units among the third to seventh lens units move, and at least one of the fourth to seventh lens units is fixed.

Abstract: The present disclosure provides a camera optical lens including eight lenses which are, from an object side to an image side in sequence: a first lens having a positive 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, a sixth lens having a positive refractive power, a seventh lens having a negative refractive power, and an eighth lens having a negative refractive power; the camera optical lens satisfies conditions of: 0.95?f/TTL; 2.00?f2/f?5.00; and ?0.90?(R13+R14)/(R13?R14)??0.25. The camera optical lens can achieve good optical performance while meeting the design requirements for long focal length and ultra-thinness.
