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 .
