Abstract
A lens apparatus for moving one or more moving lenses of a lens system up to the end position of movement by a servomotor. The lens apparatus limits the moving speed of the moving lens or lenses to a value under a predetermined level. Also, the lens apparatus gradually reduces the moving speed as the moving lens or lenses approach the end position so that the moving lens element or elements can be stopped precisely at the end position.
