A zoom lens device includes a base barrel, first and second cam barrels connected rotatably to and movable relative to the base barrel, first and second lens barrels connected respectively to the first and second cam barrels, and a driving barrel surrounding and rotatable relative to the base barrel. Rotation of the driving barrel drives the first and second cam barrels to rotate synchronously and move individually along an axis, and therefore causes individual axial movements of the first and second lens barrels along the axis.

Zoom lens device

A lens device includes a seat unit having an image sensing component, a first barrel unit, a first lens module coupled to the first barrel unit, and a second lens module mounted on the seat unit. When the first barrel unit moves toward the seat unit along an optical axis, the first lens module moves in radial directions via a first guide mechanism such that a first lens unit is misaligned with the image sensing component relative to the optical axis, while the second lens module is driven to rotate via a second guide mechanism such that a second lens unit is misaligned with the image sensing component. The lens device further includes a first biasing unit for biasing the first lens module to a first shooting position, and a second biasing unit for biasing the second lens module to a second shooting position.
