Problem

A camera lens is treated as a thin lens of focal length

f = 35\ \mathrm{mm}

in air. Its manufacturer states that, focused on an object

500\ \mathrm{mm}

in front of the lens, the transverse magnification is

-0.075

. ((a)) Using the conjugate condition, find the image distance

s_i

. ((b)) Read the transverse magnification from the matrix element

A

and compare it with the manufacturer's stated value.
