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.

摘要： A prism optical system provided with: a first prism on which a light ray coming from an objective lens is incident; a second prism on which the light ray coming from this first prism is incident, and from which this incident light ray is emitted; and a plate-like member which is interposed between the aforesaid prisms so as to provide a predetermined air space therebetween and which has a diaphragm opening and a light blocking portion. Further, an uneven portion, which consists of depressions and projections and has a serrate section, for preventing light rays, which have been reflected from the surface of the light blocking portion of this plate-like member, from entering a field stop is provided in the light blocking portion thereof. Thereby, occurrences of ghosts and flares due to stray light are prevented. Moreover, ghosts and flares are reduced.
