The Lens,it is undoubtedly the most important component and delicate part of the camera (considering the main purpose of a camera). The Lens take the beams of light bouncing off an object and focuses this light on the image plane so that a real image is formed that can be photographed.
The Film,this is a thin roll of light-sensitive plastic which is placed at the image plane of the lens. When the camera is ready to take picture, several devices combine to ensure that the film is exposed to the image formed by the lens. When the film is exposed to the image coming from the lens it records the image and we have pictures! Unknown to most people
