Patent ID: 7388715

Claim:
An imaging apparatus comprising: a zoom lens portion; and an electronic imaging device placed on an optical axis of the zoom lens portion, wherein the zoom lens portion comprises: a first lens group that has a negative refracting power and a fixed position on the optical axis with respect to the electronic imaging device; a second lens group that has a positive refracting power and is moved along the optical axis to effect focusing by correcting a change in an image formation position during a magnification change; a third lens group that has a positive refracting power and is moved along the optical axis during the magnification change; and a fourth lens group that has a fixed position on the optical axis with respect to the electronic imaging device, the first, second, third and fourth lens groups are arranged in order from an object to be imaged toward the electronic imaging device, an angle of incidence of a ray of a maximum image height incident on the electronic imaging device when the zoom lens portion is in a state at a telephoto end is not greater than an angle of incidence of the ray of the maximum image height incident on the electronic imaging device when the zoom lens portion is in a state at a wide angle end, and the angle of incidence of the ray of the maximum image height incident on the electronic imaging device when the zoom lens portion is in the state at the telephoto end is not smaller than 5°.
