The Micro-Nikkor 105mm f/2.8 operates continu-

ously from infinity («>) to 0.41m (1.34ft) for a

reproduction ratio of 1:2. With the PN-11 ring

attached, focusing is extended to a reproduction

ratio of 1:0.88.

To focus, first make sure that the tightening screw

on the focusing ring is loosened. Then, turn the fo-

cusing ring until the image on the focusing screen

appears sharp. To keep the focusing ring from mov-

ing, be sure to tighten the screw. The tightening

screw makes it difficult to accidentally move the

focusing ring, but it does not lock it in place.

The distance scale on the focusing ring is marked in

both meters (white) and feet (yellow). These figures

indicate the distance from

the subject to the

camera's film plane. The exact position of the film

plane is indicated on all cameras for convenience

when precise measurement of the distance is re-

quired. (For more details, check your camera's

instruction manual).

• Although it is possible to turn the focusing ring

with the screw tightened, do not attempt it.

• At the closest distance setting, the lens focal length

is approx. 82mm.
