Zoom lens and imaging device
By configuring seven lens groups and optimizing the optical power shift method, the problems of insufficient miniaturization and anti-shake performance of existing zoom lenses have been solved, achieving lightweight and anti-vibration effects for high-magnification zoom lenses, making them suitable for video shooting.

AI Technical Summary
Existing zoom lenses are inadequate in terms of performance, making it difficult to achieve small size and light weight, minimal change in angle of view during camera shake, and suitability for video shooting.
A seven-lens configuration is employed, with the first and fourth lens groups fixed, and the third lens group moving together with the aperture stop. The optical power and movement method of each lens group are optimized, including fixing the seventh lens group to simplify the mechanical structure and providing vibration resistance through the movement of the fourth lens group.
It achieves a small and lightweight high-magnification zoom lens, reduces the change in angle of view during shake, is suitable for video shooting, and has anti-vibration performance.
