摘要:
A zoom lens L0 includes a first lens group L1 and a rear group LR disposed in order from an object side to an image side, the first lens group L1 having a negative refractive power and the rear group LR having a positive refractive power as a whole. The rear group LR includes a partial group LP, a partial group LN, and two or more lens groups between which distances change in zooming. When image blur is corrected, the partial group LN moves in a direction including a component of a direction perpendicular to an optical axis. A lens surface closest to the object side among lens surfaces of the partial group LN and a lens surface closest to the image side among the lens surfaces of the partial group LN are both concave surfaces.
