[Background Art]
[0002]
As a zoom lens having high optical performance at a wide angle and capable of high-speed zooming, there is one having a first lens group having negative refractive power that is immovable (fixed) during zooming, a second lens group having positive refractive power, and a rear group, which are arranged in this order from the object side to the image side. Some zoom lenses also have an anti-shake function that corrects image shake by moving a lightweight lens group other than the first lens group in a direction perpendicular to the optical axis.
The present
invention provides a compact zoom lens which has a wide angle, high optical performance over the entire zoom range, and a lightweight vibration isolation group.
