摘要： This camera includes a control circuit 12 which calculates a movement amount for a focusing lens group Z.sub.1 of a zoom lens 11 based upon the photographic distance R as measured by a distance measurement device 13 and the focal length of the zoom lens 11 as detected by a focal length detection device 15, and a lens driving device 18 which then moves the focusing lens group Z.sub.1 according to this projection amount calculated by the control circuit 12. Thereby it is possible to compensate for focus deviation when zooming.
