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.
telephoto lens is more selective. The scope of its vision is
narrower, incorporating fewer objects within the frame. It too
"distorts," but in a different way than a wide-angle
lens. With a telephoto lens, objects are larger but distances
are compressed. Objects appear closer to the camera -- and closer
to one another -- than they are to the naked eye.
