Focusing / Diopter Adjustment - Leica TRINOVID 8 x 42 Notice D'utilisation

focusing / diopter adjustment

With the Leica Trinovid binoculars the central
focusing ring (4) is used to set the focus for
variously distant objects.
Compensation for individual defective vision
for viewing without eyeglasses is made using
the diopter ring (4), which is normally locked
(Figure A). To unlock the two rings the diopter
ring is pulled up (Figure B). Now, the central
focusing ring only affects the focus of the left
optical system, the diopter ring only that of
the right system.

Using one of the rings, then focus the respec­
tive barrel on the desired subject. Continue
by setting the optimum focus for the second
barrel with the other ring. Pressing the diopter
ring back down locks the set value. The set
value can be conveniently read from the accu­
rate scale on the diopter ring.
