ABSTRACT:
A lens barrel assembly (30) is described that includes a hollow lens barrel (3), at least one lens (4) and a filter (5). The lens barrel has a mounting portion (311). The at least one lens is received in the lens barrel, and the filter is transversely mounted in the lens barrel along a direction perpendicular to an axis of the lens barrel such that the filter interferingly engages in the mounting portion. In use of the lens barrel assembly, it is not necessary to adhere the filter to the lens barrel. Accordingly, the pollution problem of the filter and the lenses is eliminated, the manufacture of the lens barrel assembly is simplified, and the manufacturing cost is decreased.
