Claim:
An imaging apparatus comprising: an image pickup device configured to convert a subject image into an electric signal; a rear-focus zoom lens system configured to form a subject image on the image pickup device including a zoom lens; and a focus lens; a focus-lens driving device configured to drive the focus lens; a storage device configured to store, for a given subject distance, a plurality of groups of locus information, each group corresponding to a different kind of light source, indicating a correlation between the zoom lens position and an in-focus position of the focus lens; a subject-distance detecting device configured to determine the distance of a subject on the basis of the zoom lens position and the focus lens position; and a controller configured to control the driving of the focus lens on the basis of the correlation information stored in the storage device, wherein the controller determines a locus information to be used, according to the subject distance detected by the subject-distance detecting device, by selection from the groups of locus information or calculation based on the groups of locus information stored in the storage device, wherein each group of locus information corresponds to an associated light source.
