Abstract
A focus adjusting device for a camera having a varifocal optical system includes a pivotal member having a focusing guiding slot. The pivotal member is movable about a fixed pivot on the camera body. A guide pin fits in the guiding slot of the pivotal member and zoom information transmitting means are provided for moving the guide pin in accordance with the focal length of a zoom lens unit to vary the distance from the pivot to the pin. Focusing means are included for varying the position of the pivotal member according to a set subject distance along with focus coupling means for moving a focus lens unit in corresponding relation to the position of the guide pin with respect to the direction of the optical axis. The device, which is compact, compensates for differences in the focusing position of the focus lens unit due to variations in the focal length.
