Cal cu lat ing Picture Angle

The size of the area exposed by a 35-mm

camera is 36 × 24 mm. The size of the

area exposed by the D70, in contrast,

is 23.7 ×15.6 mm. As a result, the picture

angle of photographs taken with the D70

differs from the picture angle for 35-mm

cameras, even when the focal length of

the lens and the distance to the subject

are the same.
