FOREWORD
Unlike other Nikkor fishe ye lenses producing a cir-
cul ar image , the Fisheye-Nikkor 16mm f/2_8 lens
fills up the frame with an image _ But it still pos-
sesses a 180
0
angle of view (as measured across the
diagonal) an d gives you the same exciting fisheye
effects as regular fisheye lenses_
Weighing in at 330 grams, this lens is light enough
to carry a nywhere for special effects or ali-encom-
passing views as in advertising, industrial , or travel
photography . With a maximum aperture of f/2 .8 ,
the 16mm Fisheye provides a bright and easy -to-
focus image in the viewfinder. And because coma
has been so well corrected, it can be used wide
open for sharp ava ilable light or night shots. Other
features include automatic maximum aperture in-
dexing (AI) with AI-type Nikon and Nikkormat
cameras* and a seco nd ary aperture scale for aper-
ture direct readout (ADR) in the finder of suitably
equ ipped cameras. Four rear-m ounting bayonet-
type filters (L 1 Be, 056, A2, and B2) are supplied
with this lens as standard equipment; one must be
attached to the lens at all times.
* All AI -Nikkor lenses have a mete r coupling shoe
for use with non-AI-type cameras. However ,
8 maxi mum aperture index ing is still required.
MOUNTING THE LENS A
Posi tion the len s 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 re-
lease button on the camera and twist the lens
clockwise.
Note: When mounting the lens on a came ra wit h a meter coupling
lever (AI type), make sure that the came ra 's meter coupling lever
is correctly positioned; when mounting on a ca mera without this
leve r (non-A I type), " manual " m ax imum aperture indexing is re-
quired. In both cases, refer to the came ra's instruction manual.
AUTOMATIC APERTURE DIAPHRAGM- B
The Fisheye-Nikkor's automatic diaphragm couples
directly to the thru-the-Iens meter of a ny F2 Nikon
Photomic or Nikkormat camera for full aperture
ex posure measurement via a meter coupling ridge
for AI cameras or a meter coupling shoe for non-AI
cameras. The aperture ring has click-stop settings
for each full f-stop from f/2 .8 to f/22 and can also
be set to intermediate openings for more precise
exposure. An "aperture-direct-readout" scale is
also engraved on the lens to allow direct reading of
the aperture setting in suitably equipped camera
finders. The procedure for exposure measurement
is sim ilar to that used with other Nikkor lenses fea-
turing automatic diaphragms. For details, see the
instruction manual supplied with your camera or
Photomic finder.
