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 D3400, 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 D3400. The approximate focal length of lenses for the D3400 in 35mm format can be calculated by multiplying the focal length of the lens by about 1.5.
