Week 8: Camera Lenses
The lens determines what the camera can see. One type of lens can provide a wide vista even though you may be relatively close to the scene; another type may provide a close view of an object that is quite far away. Different types of lenses also determine the basic visual perspective—whether you see an object as distorted or whether you perceive more or less distance between objects than there really is. They also contribute to a large extent to the quality of the picture and how much you can zoom in or out on an object without moving the camera.
