Abstract:
1. A lens apparatus comprising: a first lens barrel holding a lens; a second lens barrel disposed on an image side further than an object side end portion of the first lens barrel in an optical axis direction and assembled to the first lens barrel so as to allow a movement of the first lens barrel in the optical axis direction; a driving member that moves the first and second lens barrels in the optical axis direction; a positioning member fixed to one of the first or second lens barrel; and an elastic member disposed between the first and second lens barrels and that generates a biasing force to bias the first lens barrel toward an object side from the second lens barrel, wherein the biasing force brings the other of the first or second lens barrel in contact with the positioning member to position the first lens barrel at a predetermined object side position with respect to the second lens barrel in a state where a movement of the first lens barrel on the image side due to an external force is allowed.
