BEFORE USING THE LENS
(Read the following carefully and get the most out of your new lens now and in the
many years to come.)
For its focal length, your Reflex-Nikkor 500mm f/8 is so compact and light you can
use it even in hand-held shooting. That's because the lens adopts what is known as a
"catadioptric" optical construction in which light is reflected and refracted by a com-
bination of mirrors and lenses to form the image you see in the camera's viewfinder.
Not only is the lens barrel unusually short-chromatic aberration correction is so out-
standing you won't have to adjust focus for infrared photography. And at the fixed
aperture of f/8, you have ample depth of field.
As has become customary with Nikkor lenses, all air-to-glass surfaces of your lens have
been coated with NIC (Nikon Integrated Coating) to just about banish picture flare and
ghost. And you'll see the results in the photos you take: superb contrast and natural-
looking color. Great special effects, too-you can take pictures in which unfocused
elements come out with interesting ring-shaped highlights.
And what a surprise . . . you can actually focus a lens this long down to just 1.5m (5ft),
with a reproduction ratio of 1:2.5X. Also, the lens comes with a set of five filters, with
one already mounted on the rear of the lens and the other four cleverly concealed in-
side the beautiful hard case you use to store the lens. These filters include a neutral
density filter that will give the effect of stopping the lens down to f/16; for details,
read the section on filters.
MOUNTING THE LENS A
To mount the lens on the camera, position it in the camera's bayonet mount so that
the mounting index dots on the lens and camera body are aligned. Then, twist the
camera body clockwise until it clicks and locks into place. To remove the lens, press
the camera's lens release button and twist the camera counterclockwise.
MOUNTING ON THE TRIPOD
For maximum picture sharpness and freedom from camera shake, the use of a tripod is
recommended. The Reflex-Nikkor 500mm f/8 is fitted with a sturdy, fully rotatable
(360°) tripod mounting collar for just such purposes. To attach to the tripod, position
the collar's tripod socket on the tripod screw and tighten. To rotate the lens (with
attached camera) for vertical or horizontal format, loosen the collar locking screw,
rotate the lens to the desired position, and retighten the collar locking screw to secure
the assembly. For precise positioning, click-stop positions are provided at 90° intervals.

Focusing is as simple as turning the focusing ring © until the image on the focusing
screen appears crisp and clear.
To prefocus the lens, turn the focusing ring to the required distance. Note that there
are two focusing distance scales © and two corresponding distance indices©©. For dis-
tances from - (infinity) to 2.5m (8ft), read off the scale next to the camera body,
