FOCUSING - continued
Focusing at a Predetermined Ratio
Above the distance scales on the focusing ring
is the reproduction ratio scale inscribed in
orange. The scale, with figures from 1:10 to
1:2, represents the reproduction ratios ob-
tained when the lens is used alone.
Using this scale, you can photograph at a pre-
determined ratio without calculating the dis-
tances required. To photograph at a reproduc-
tion ratio of 1:5, for example, just turn the
focusing ring until the orange-colored number
"5"
is aligned with the distance scale index;
then aim at the subject and adjust your
posi-
tion (close to, or farther away from, the sub-
ject) until the image appears sharp and crisp
on the focusing screen.
When the Nikon Teleconverter TC-301 is at-
tached,
the reproduction ratio increases to 1:1
and the automatic diaphragm still functions as
before.

Reproduction Ratio
The reproduction ratio is the numerical ex-
pression of the relationship between the image
size and the actual size of the subject. For
example, if the image on the focusing screen is
one-fifth the actual size of the subject, the
reproduction ratio is said to be 1:5, and is
indicated on the reproduction ratio scale of
the Micro-Nikkor 200mm f/4 by the number
"5."
