Title:
ズームレンズおよびそれを有する撮像装置
Document Type and Number:
Japanese Patent JP6977007
Kind Code:
B2
Abstract:
A zoom lens L0 includes a first lens unit L1 having a positive refractive power, a second lens unit L2 having a negative refractive power, a third lens unit L3 having a positive refractive power, an intermediate lens group LM including a plurality of lens units, and a last lens unit LR having a negative refractive power. An interval between the adjacent lens units changes during zooming. The zoom lens L0 includes an aperture stop SP. The intermediate lens group LM includes a negative lens unit LN having a negative refractive power. Both the negative lens unit LN and the last lens unit LR move to an object side during zooming from a wide-angle end to a telephoto end. The zoom lens L0 satisfies predetermined conditional inequalities.
