Abstract

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.
