MOUNTING THE LENS A
Align the green aperture index © on the lens with the mounting index on the
camera and insert the lens in the camera's bayonet mount. Then twist the lens
counterclockwise until it clicks into place. (To remove, depress the lens release
button on the camera and twist the lens clockwise.)
Notes:
1) When mounting the lens
on
an Al-type camera with a meter coupling lever, make
sure the lever is in the "down"
position;
when mounting on a camera without this
lever (non-AI type), "manual" maximum aperture indexing is required- For more
information, refer to the camera's instruction manual.
2) When the lens is used with the Nikon F-401/N4004, the camera meter coupling
function does not operate and the exposure indicator LEDs do not appear.
FOCUSING B
To focus, rotate the focusing ring ® until the image in the viewfinder appears
sharp and crisp.
For pinpoint focusing, focus with the lens in the 70mm position, then move back
to the best focal length for the desired picture composition.
ZOOMING C
This allows you to
'trim'
your picture to fit the frame exactly. To zoom in and out,
look through the viewfinder and turn the zooming ring (?) to the right and left until
the desired composition is framed on the focusing screen. For reference, a three-
position scale to indicate focal length settings (35mm, 50mm and 70mm) is
engraved on the zooming
ring,
but you can also use intermediate settings.
MACRO FOCUSING
Although normal focusing is possible from infinity to 0.5m
(2
ft),
you can focus
even closer at any focal length setting with a smooth action of the focusing
ring.
The orange "M" and line (?) indicate macro mode focusing. The minimum focal
distance and maximum reproduction ratio are 0.35m (1 ft) and 1:4.4 respec-
tively.
At a focal length of 70mm, its reproduction ratio is
1:4.4,
while at 35mm, it
becomes 1:8.3.
It is recommended to use longer focal lengths as much as possible for macro
focusing,
because vignetting may occur at shorter focal length settings.
Note:
Although this lens has macro focusing capability, a Micro-Nikkor lens is
recommended for document copying or slide duplication where critical sharp-
ness is required.
