[] Calculating Angle ofView
The size ofthe area exposed by a 35 mm camera is36 x24 mm. The size of the area exposed
by the D7000, in contrast, is23.6 x 15.6 ram, meaning that the angle of view of a 35mm
camera isapproximately 1.5times that ofthe D7000. The approximate focal length of lenses
for the D7000 in 35mm format can be calculated by multiplying the focal length ofthe lens
by about 1.5.
