FOCUSING — continued

Focusing at Predetermined Ratio

Above the distance scale on the focusing ring

are two reproduction ratio scales inscribed in

orange. The inner scale, with figures from 1:10

to 1:2, represents the reproduction ratios ob

tained when the lens is used alone. The outer

scale figures (i.e., 1:2 to 1:1) represent the

ratios possible when the lens and, PN-1 or

PN-11 ring, are used together. Using either of

these scales, you can photograph at a pre

determined ratio without calculating the

distances required. To photograph at a repro

duction ratio of 1 : 5, for example, just turn

the focusing ring until the number “5” is

aligned with the distance scale index; then

aim at the subject and adjust your position

(close to, or farther away from, the subject)

until the image appears sharp and crisp on

the focusing screen.
