摘要:
A zoom lens includes first, second, and third lens groups having positive, negative, and positive refractive powers, respectively, which are arranged in order from the object side to the image side. When zooming from wide-angle to telephoto, the first lens group moves to the object side, and spacings between the lens groups change. The third lens group has at least two lenses including a positive lens arranged closest to the object side. Blur correction on the image plane is performed by moving the positive lens of the third lens group perpendicularly to the optical axis. The zoom lens satisfies the following conditional expression (1): 0.3
