FOREWORD
Representing a true breakthrough in lens
design,
the Micro-Nikkor 200mm f/4 IF is the
world's first 200mm "micro" lens. By utiliz-
ing internal focusing (IF), a system in which
the lens elements move inside the lens, there
is absolutely no increase in the overall length
of the lens barrel as the lens is focused closer.
Therefore, it is extremely easy to handle.
At its closest focusing distance of 0.71m
(2.34 ft.), the lens produces a 1:2 reproduc-
tion ratio. When the Nikon
TC-301
Teleconvert-
er is used, full life-size images (1:1) are possi-
ble (with
a
decrease in the effective aperture to
f/8).
This lens is very light-weight and has its
own built-in telescoping lens hood and detach-
able tripod mounting collar.

Because of its 200mm focal length, this lens
offers tremendous free-working distance, so
that you can take close-up shots of shy or
dangerous subjects, like butterflies or poison-
ous snakes, and still keep your distance. Even
at 1:2 magnification, the free-working dis-
tance is approximately 50cm (19.5 in.) be-
tween the front of the lens and the subject.
It also focuses to infinity, making it perfect
for use as a regular 200mm telephoto lens.
In addition, NIC (Nikon Integrated Coating)
is applied to the air-to-glass surfaces of lens
elements to reduce ghost images and flare and
improve contrast.
