A variable focal length objective comprises a casing 19 which houses a movable mount 8 and a fixed mount 1, each of which mounts carries a group of optical components, the mounts being fitted together in such a way that the optical components of both mounts alternate in a given sequence while their optical axes coincide to form the optical axis of the objective, the section of the outer surface of at least one of the mounts which contacts the casing 19 having an angular dimension not greater than 180 degrees with respect to the optical axis of the objective. The fixed mount 1 is provided with seatings 2, 3, 4 for optical components 5, 6, 7 while the movable mount 8 is formed with seatings 9, 10 for optical components 11, 12. The two mounts are assembled, in a direction at right angles to the optical axis, and their outer surfaces form a cylinder. The relative axial positions of the two mounts are varied by means of a pin screwed to the mount 8 through a slot 21 in the cylindrical casing 19.
