The focal length of the lens also makes a difference. A wide-angle lens is highly inclusive. It incorporates within the frame a multitude of subjects, but it does so at the cost of a certain distortion. Objects which are nearer become large, leaving objects in the background small. Also, the shapes of objects at the corners of the frame are altered.
Circles become ellipses.
A telephoto lens is more selective. The scope of its vision is narrower, incorporating fewer objects within the frame. With a telephoto lens, objects are larger but distances are compressed.
