DESCRIPTION OF THE P
These are special lenses that are designated for digi
tal cameras because the lens image
circle is designated to correspond t
o the size of the image sensors of most digital SLR
cameras. The specialized design gives these lens
es the ideal properties for digital cameras.
An image sensor element larger than those correspo nding to APS-C cannot be used in
digital cameras or 35mm SLR cameras. If such an element i
s used vignetting will occur
on the picture surface.
If you use SD14 or SD10 or SD9 digital camera, c orresponding angle of view will be
TT ACHI NG TO CA MERA BODY

y function in the same way
as your normal lens.

AND ZOOMIN G
For autofocus operation, set the fo
cus mode switch on the len s to “AF” position.
If you wish to focus
manually , set the foc us mode switch on t he lens to the “MF” position.
ou can adjust the focus by turning the focus ring.
T o avoid damagin g AF mechanism, plea se do not turn the fo cus ring manually while in
the autofocus mode.
The viewfinder of so me Nikon AF cameras ha ve indicators to displ ay the focus status.
● ” symbol indicates that correct fo cus has been set, “
” indicates that focus is
set in front of the sub
ject, and “
” indi cates that focus is set behind the subject. W hen
this AF lens is used
with Nikon AF came ras in MF mode, ple ase adjust the lens’ focus
until the “
● ” symbol is visible.
When operating this l ens in manual focus mode, it is recommended that correct fo cus be
confirmed visually in the viewfi
nder rather than relying on the distance scale. This is
due to possible focus shift resulting from extreme c
hanges in temperature which cause
various components in the lens to expand and contact.
Special allowance is made for
this at the infinity setting.
Rotate the Rubber grip on the zoom ring t
o the desired position.
Zoom Lock Switch》

om Lock Switch to eliminate the zoom creep when the
lens is tilted down. Please
set zooming ring to 18mm and set the zoom lock switch to the
LOCK ” position. (fig.2)
The indication of the
lens as “1:xx” on a fo cusing distance scale represent the magnification
(commonly called the reproduction ratio). For example
when you are in focus at the
“1:3.9” position on the scale, a subjec
t with an actual size of 3.9cm will have an image size
of 1cm on the firm. (fig.3)
