Abstract
An optical system comprises a first lens element and a second lens element which are respectively shiftable to have a component in a direction perpendicular to the optical axis, the second lens element being composed of the first lens element and other lens element, and the first lens element or the second lens element being shifted to have a component in a direction perpendicular to the optical axis, thereby carrying out a correction of the image plane. Thus, there are provided an optical system having a suitable vibration reduction property, an image apparatus equipped with the optical system and a method for manufacturing the optical system.
Claims23
An optical system comprising a first lens element which is shiftable to have a component in a direction perpendicular to the optical axis and a second lens element which is shiftable to have a component in a direction perpendicular to the optical axis,
- said second lens element comprising said first lens element and other lens element, and
- said first lens element or said second lens element being shifted to have a component in a direction perpendicular to the optical axis,
- said first lens element being shifted relative to said other lens element upon said first lens element shifting thereby carrying out a correction of the image plane.
A method for manufacturing an optical system comprising a first lens element and a second lens element, including steps of:
- composing said second lens element by said first lens element and other lens element,
- disposing said first lens element to be shiftable such that a component in a direction perpendicular to the optical axis is included, and said second lens element to be shiftable such that a component in a direction perpendicular to the optical axis is included, said first lens element is shifted relative to said other lens element upon said first lens element shifting, and
- composing said first lens element and said second lens element such that a correction of an image blur may be performed by shifting either said first lens element or said second lens element to have a component in a direction perpendicular to the optical axis.
