Patent ID: 11914123

Abstract:
The present disclosure relates to a technical field of optical lenses, and discloses a zoom lens. The zoom lens, being sequentially from an object side to an image side, includes a first lens having a negative refractive power, a second lens group having a positive refractive power, a fifth lens having a positive refractive power, and a sixth lens having a negative refractive power, when zooming, among the first lens, the second lens group, the fifth lens, and the sixth lens, a spacing in an optical axis direction of adjacent lenses or lens groups changes, the second lens group includes a second lens having a positive refractive power, a third lens having a negative refractive power, and a fourth lens having a negative positive power. During photographing, when an F number (FNO) of a wide-angle end is less than or equal to 2.0, the zoom lens becomes bright.
