A taking lens apparatus has a zoom lens system that forms an optical image of an object at a variable magnification and that includes an aperture stop in the optical path, and an image sensor that has a light-receiving surface that converts the optical image into an electrical image signal and outputs it. The zoom lens system includes an optical member having a reflective surface that reflects a light beam in such a way that the optical axis is bent at substantially 90&#xb0;. Moreover, prescribed conditions are fulfilled among the focal length of the entire zoom lens system at the wide-angle end, at the telephoto end, the axial distance from the image plane to the exit pupil at the wide-angle end, and the axial distance from the image-side surface of the most image-side lens element to the image plane.

Taking lens apparatus

An image-taking lens apparatus has an image sensor for converting an optical image of a subject into an electrical signal and an image-taking lens system for forming the optical image on the image sensor. The image-taking lens system includes a prism for bending the optical path, and the refractive index of the prism fulfills a prescribed conditional formula.

Image-taking lens apparatus

A zoom lens system for forming an optical image of a subject on the light-receiving surface of an image sensor that converts the optical image into an electrical signal is provided with, from the object side thereof, at least a first lens unit, a second lens unit, and a third lens unit, and achieves zooming by varying the distances between the lens units. The first lens unit has a negative optical power. The second lens unit has a positive optical power. A prescribed condition is fulfilled.

An imaging lens device has an imaging lens system that forms an optical image and an image sensing device that converts the optical image formed by the imaging lens system into an electronic signal. The imaging lens system includes two lens elements each made of a homogeneous material and having a positive optical power, and fulfills the following condition: 1.25&#x3c;L/f&#x3c;2.00, where L is the distance from the most object side lens surface to the image plane, and f is the overall focal length of the lens system.
