FOREWORD
The Micro-Nikkor 105mm f/4 is a special telephoto lens designed for
close-up photography at high reproduction ratios. It features the same
optical construction as the much-acclaimed Bellows-Nikkor 105mm
f/4,
but with a special focusing helicoid that enables operation from
infinity (°°) to a reproduction ratio of 1 : 2 (half life-size) without the
need for any adapters. The lens offers "automatic maximum aperture
indexing"

gether to permit full aperture exposure measurement; the lens is also
fitted with a meter coupling shoe to permit the same operation with
Nikon cameras which lack the Al facility. In terms of optical performance,
feature, enabling virtually distortion-free images at all reproduction
ratios.
hances performance by increasing image contrast, while reducing flare
and ghost, for outstanding color reproduction.
When the Micro-Nikkor 1 05mm is used with the special Auto Extension
Ring PN-11 or PN-1, focusing is further extended from 1 : 2 to 1 : 1 for
full life-size reproduction.
To get the best results from your Micro-Nikkor 105mm f/4, read this
instruction manual carefully. Keep the manual handy for reference

MOUNTING THE LENS
Position the lens in the camera's bayonet
mount, aligning the mounting indexes on the
camera and the lens. Twist the lens counterclockwise until it clicks into place.
To remove, depress the lens release button on
the camera and twist the lens clockwise.
Note:
When mounting the lens on a camera with a
meter coupling lever (Al type), make sure that the
camera's meter coupling lever is correctly positioned;
when mounting on a camera without this lever (non-
Al type), conventional "manual" maximum aperture
indexing is required. In both cases, refer to the
camera's instruction manual.
