Calculating Angle of View
The size of the area exposed by a 35mm camera is 36 × 24 mm. The size of the area exposed by
the D3100, in contrast, is 23.1 × 15.4 mm, meaning that the angle of view of a 35mm camera is
approximately 1.5 times that of the D3100. The approximate focal length of lenses for the D3100
in 35mm format can be calculated by multiplying the focal length of the lens by about 1.5.
