FOREWORD
The Reflex-Nikkor 1000mm f/11 is a super-telephoto catadioptric-type lens offering
exceptionally compact size that makes for easier, even hand-held shooting. The use of a
mirror construction in this lens makes for the drastically reduced overall length, and
also provides for excellent correction of chromatic aberration (normally high in a lens
of this focal length); chromatic aberration correction afforded by the Reflex-Nikkor is
so great, in fact, that this lens does not require refocusing for infrared photography.
Further enhancing optical performance is the use of NIC (Nikon Integrated Coating)
on air-to-glass surfaces; with NIC, flare and ghost are effectively controlled for out­
standing results. The rear of the lens is fitted with a threaded mount that accepts
Nikon 39mm screw-in filters (five are provided with the lens); this feature is particular-
iy useful for control of exposures via neutral density (ND) filters (the lens has a fixed
aperture) of various densities. Other features of the Reflex-Nikkor 1000mm f/11
include the built-in tripod mounting collar, the slip-out lens hood, and close focusing
to 8m (25 ft).
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 chcks 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 1000mm f/11 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 B
Focusing with the Reflex-Nikkor 1000mm f/11 is particularly easy due to the compact
lens size. And, as a further aid, the focusing ring is provided with two threaded mount­
ing locations for attachment of the focusing handle at the point most convenient for
operation. Simply screw the handle into the ring at the desired location and turn the
ring via the handle until the image appears sharp and crisp in the camera’s focusing
screen. It should be noted that the focusing ring can be turned 10° past the normal
infinity position to take into account the coefficients of expansion and contraction.
