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×).
