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.
