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.
