Abstract
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.
