Provided is a zoom lens system comprising a plurality of lens groups one lens group of which is moved to perform zooming. A specified lens group among the lens groups is a focusing lens group. The zoom lens system comprises: a normal photography mode in which focusing is carried out from infinity to a predetermined photographing distance by continuously moving the focusing lens group of the specified lens group; and a shifting mode which shifts from the normal photography mode to a macro photography mode by moving at least one lens element of the specified lens group other than the focusing lens group when focusing on an object at a photographing distance that is shorter than the predetermined photographing distance of the normal photography mode. When the zoom lens system is in the macro photography mode, focusing is carried out from the predetermined photographing distance to a minimum photographing distance by continuously moving the focusing lens group. |
