摘要: A zoom lens system includes, in order from the object side, a negative first lens group, a positive second lens group; and a positive third lens group. The first lens group includes, in order from the object side to the image side, a negative first lens and a positive second lens. The second lens group includes, in order from the object side to the image side, a positive third lens, a negative fourth lens, and a negative fifth lens. The zoom lens system satisfies certain conditions related to the configuration of the lens and lens groups of the zoom lens system in order to provide a compact zoom lens having excellent correction of aberrations.

摘要: A zoom lens includes, in the order from the object-side to the image-side thereof, a first lens group of a negative refractive power, a second lens group of a positive refractive power, and a third lens group of a positive refractive power. The first lens group includes, in the order from the object-side to the image-side thereof, a first lens of negative refractive power, and a second lens of positive refractive power. The second lens group includes, in the order from the object-side to the image-side thereof, a third lens of positive refractive power, a fourth lens of negative refractive power, and a fifth lens of negative refractive power.
