<p><P>PROBLEM TO BE SOLVED: To provide a photographic lens which can excellently correct various aberrations, can minimize the change of performance when a lens is shifted, is compact and is excellent in optical performance over the whole screen; and to provide an optical instrument with the photographic lens, and a method for manufacturing the photographic lens. <P>SOLUTION: The photographic lens includes an object side lens group G1 and an image side lens group G2 arranged at an air interval from the object side lens group G1 in order from an object side. At least part of the image side lens group G2 is moved along an optical axis direction as a focusing lens group, to perform focusing from a far-distance object to a near-distance object and at least part of the image side lens group G2 is moved to have a component in a direction almost orthogonal to an optical axis as a shift lens group, thereby achieving a vibration control. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
