A zoom lens and an imaging device
Document Type and Number:
Japanese Patent JP6045443
Kind Code:
B2
Abstract:
A zoom lens includes: a positive first lens group; a negative second lens group; and a positive third lens group. The first through third lens groups move such that the distance between the first lens group and the second lens group is greater, and the distance between the second lens group and the third lens group G3 is smaller at a telephoto end compared to a wide angle end. The third lens group is constituted by a positive 3-1 lens group and a 3-2 lens group. The 3-1 lens group is fixed when camera shake occurs and during focusing operations. The 3-2 lens group includes a shake preventing lens group that moves in a direction perpendicular to an optical axis to correct camera shake, and a focusing lens group provided toward an image side of the shake preventing lens group that moves along the optical axis during focusing operations.
