The illustrations in Figures 7.21–7.25 demon-

strate that lens coverage dot areas are tailored to t

specic sensors. A 50mm lens designed for a 65mm

sensor produces a much larger coverage area than a

50mm lens designed for a 16mm lm coverage area,

but both lenses are 50mm lenses! A 50mm lens on

a 65mm camera is actually a very wide-angle lens,

while on a VistaVision or Full Frame sensor it is a

modestly wide-angle lens. A 50mm lens on a 35mm

or Super 35mm camera is a normal lens, but on a

16mm camera it is a modestly telephoto lens. Focal
