摘要： The invention relates to a zoom lens and an imaging apparatus incorporating the same. The zoom lenses comprises, in order from its object side, a positive first lens group G1, a negative second lens group G2, a positive third lens group G3, and a positive fourth lens group G4. Zooming is implemented by changing the spacing between the respective lens groups. Upon received in a lens mount, the third lens group is shifted and positioned while its optical axis is tilted at an angle of ±45° with those of other lens groups or placed substantially horizontal. At least one of lenses in the second lens group G2 or the fourth lens group G4 is configured such that a portion of that lens proximate to the third lens group being received in the lens mount is cut away. The following condition (1) is satisfied: 0.3

摘要： An image pick-up apparatus includes an optical system which forms a subject image. An image pick-up unit obtains image data from the subject image formed by the optical system. A vibration detecting unit detects a vibration of the image pick-up apparatus. In an image deterioration information storage unit, information of image deterioration generated by the optical system is stored. An image deterioration correcting unit corrects the image deterioration generated by the optical system with respect to the image data output from the image pick-up unit in accordance with the image deterioration information stored in the image deterioration information storage unit. A vibration restoring unit restores the image deteriorated by the vibration with respect to the image data output from the image deterioration correcting unit in accordance with the vibration detecting signal of the time series.
