A 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 D5500, in contrast, is 23.5 × 15.6 mm,
meaning that the angle of view of a 35mm camera is approximately 1.5
times that of the D5500.
The approximate focal length of lenses for the
D5500 in 35mm format can be calculated by multiplying the focal
length of the lens by about 1.5.
