The important magnification values on the power
ring are black on white in order to simplify reading
and adjusting the power ring under difficult lighting
conditions.
Diopter adjustment
The purpose of the diopter adjustment is to adapt
the scope to the user’s eye and to compensate for
individual visual acuity. If corrective glasses are worn
while shooting, the glasses must also be worn when
adjusting the diopter.
The MINOX ZP5 has a lock ring to prevent inadvertent
turning of the diopter adjustment ring, e.g. when twist-
ing the eyepiece protection cap into position. Turn the
ring counter-clockwise to release the locking mecha-
nism and clockwise to lock the diopter adjustment ring
into place. This lock is designed to prevent accidental
adjustment of the diopter. However, under use of great
force, the diopter adjustment can still be turned.
Note:
When making adjustments to your riflescope,
be sure to follow the safety precautions of the rifle
manufacturer.
To adjust the diopter, turn the magnification to the
highest power and loosen the lock ring. Aim the ri-
flescope at a uniformly bright object in the distance
like the overcast sky. Turn the diopter adjustment ring
until the reticle is sharply focused. Look past the ri-
flescope at the distant object and then through the
riflescope – the reticle should be perfectly sharp. If the
reticle appears sharp only after a moment of looking
through the riflescope, the diopter is not correctly ad-
justed. Although the eye can compensate somewhat
for a sub-optimal setting, this can nevertheless result
in eye fatigue under prolonged use.
This diopter setting can now be locked into place with
the lock ring and will have to be adjusted again only
with changing eyesight.
Parallax adjustment
Parallax is the visible movement of the reticle over
the target image. This occurs when the observing eye
moves vertically or horizontally behind the riflescope
and the scope has not yet been adjusted parallax-free
to the target distance. This movement is also called
parallax error and is a displacement of the apparent
position of an object viewed along two different lines
of sight. Parallax occurs when the plane of the target
image in the scope is not at the same distance as the
plane at which the reticle is visible. This difference
causes the reticle in relation to the target image to
appear out of focus.
The MINOX ZP5 riflescopes are equipped with a paral-
lax adjustment knob to compensate for parallax errors
from 50 m to infinity. The focus of the target image is
adjusted to match the focus of the reticle. Parallax er-
ror is eliminated by bringing the focused target image
into the same image plane as the reticle.
To determine if the target image is parallax-free at
the desired distance, move your head up and down,
and from side to side while looking through the rifle-
scope. This will cause the eye pupil to move within
the exit pupil of the riflescope. If the reticle moves
but the target image does not (the rifle must be kept
absolutely steady), then the parallax error has not
been sufficiently corrected.
If the reticle moves in the opposite direction than the
movement of the head (e.g. the head moves to the
left, the reticle moves to the right), then the target is
farther away than the parallax-free distance. In this
