Parallax Compensation - Leica ER 2,5–10x42 Anleitung

parallax coMpensatIon

Leica ER 2.5–10 x42 riflescopes are set parallax-
free to a distance of 100m, as is usual for models
with magnifications ≤12x. In other words, you can
simultaneously see the reticle (following dioptric
compensation, see previous section) and a target at
this distance with perfect sharpness, regardless of
whether or not your eye is in the exact optical axis
of the riflescope. Deviations of the impact point as
a result of the eye not being precisely centered are
generally negligible.
However, these deviations have to be taken into
account for significantly greater or smaller target dis-
tances, which is why riflescopes with magnification
ranges beyond 12x, like the LEICA ER 3.5–14x 42
for example, have an additional setting option for
these kinds of distances: parallax compensation.
On the left side of the scope tube, turn the parallax
adjusting ring (7) until the image of the target and
the reticle are both displayed in sharp focus(or so
that the engraving for the required distance on scale
7a is opposite index 7b). For the most accurate
setting possible, we recommend always using the
greatest magnification. You have achieved the ideal
setting when the reticle and the image do not move
towards one another if you change the position of
your eye in relation to the eyepiece.
