Most photographic lenses can be thought of as modified pinhole lenses. A pinhole lens would be excellent except for a few serious limitations.

Most photographic lenses can be thought of as an answer to the question "how can we modify a pinhole lens to buying camera lens admit more light and give higher resolution?" A first step is to put a simple convex lens at the pinhole with a focal length equal to the distance to the film plane buying camera lens (assuming the camera will take pictures of distant objects). This allows us to open up the pinhole a bit. The geometry is almost the same as with a simple pinhole lens, but rather than being illuminated by buying camera lens single rays of light, each image point is illuminated by a focused "pencil" of light rays.
