Cameras use combinations of lenses to create an image for recording. By the end of this section, you will be able to: Describe the optics of a camera. Characterize the image created by a camera.
Even a short object distance such as the length of your hand is two orders of magnitude larger than the lens’s focal length, resulting in minute variations of the image distance.

(The 50-micron difference is smaller than the thickness of an average sheet of paper.) Such a small difference can be easily accommodated by the same detector, positioned at the focal distance of the lens.
