Lesson 2/Learning Event 3
Learning Event 3:
DETERMINE THE ANGLE OF VIEW FOR A GIVEN FOCAL LENGTH LENS
1. The focal length of a lens determines its angle of view.
As the focal
length increases, the angle of view decreases (fig 2-7).
Figure 2-7. The angle of the 50mm lens is
one-half that of the 25mm lens
2.
The wider the angle of view, the more subject area is covered (fig 2-8).
