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 D7100 when DX (24×16) is selected for Image area in the shooting menu, 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 D7100 (when 1.3× (18×12) is selected, the size of the area exposed is
reduced and the angle of view is reduced by a further 1.3×).
